Some texlive- packages fail to build non-deterministically. This one is

on powerpc64le-linux from current master (commit

d904abe0768293b2322dbf355b6e41d94e769d78), but ISTR we saw the same kind

of problem on other architectures before:

Notice the “realloc” message (from glibc) suggesting heap corruption.

Often, simply retrying yields a successful build.

I just tried building core-updates after the upgrade to TeX Live 2020
(core-updates commit f72a125) and texlive-amscls failed with a slightly
different error coming from glibc, but still indicative of heap corruption:
“corrupted size vs. prev_size”

Full build output attached, and relevant snippet below:

I’ll keep trying to run valgrind on it to see where the corruption happens.

Hello,

I was able to do a build of texlive-amscls with `export MALLOC_CHECK_=2`, 
and a core dump was generated. I managed to get a guix environment with 
debuginfo for texlive-bin, but for some reason it still doesn’t have 
debug info for glibc available. FYI, this was the command line I used:

$ guix environment texlive-amscls --with-debug-info=texlive-bin \
	--ad-hoc valgrind gdb glibc:debug

Valgrind isn’t working because of the lack of glibc debug info, but I was 
able to get the backtrace below from the core file, using GDB. I am yet to
analyse it and see if it provides any clue:

Core was generated by `luatex amsclass.ins'.
Program terminated with signal SIGABRT, Aborted.

Hello,

While investigating luatex crashes in the TeX Live 2020 package of

GNU Guix¹, we identified the following heap corruption reported by

Valgrind (this is on GNU/Linux, with glibc 2.33):

[...]

valgrind: m_mallocfree.c:305 (get_bszB_as_is): Assertion 'bszB_lo == bszB_hi' failed.
valgrind: Heap block lo/hi size mismatch: lo = 1232, hi = 68.
This is probably caused by your program erroneously writing past the
end of a heap block and corrupting heap metadata.  If you fix any
invalid writes reported by Memcheck, this assertion failure will
probably go away.  Please try that before reporting this as a bug.

Does that ring a bell? Is there a chance this problem was fixed in the

meantime?

Thanks in advance,

Ludovic.

texlive-* packages fail to build non-deterministically

Recipients:(address . 48064@debbugs.gnu.org)

Message-ID:3617506.ZDHn73UUgp@popigai

I have bad news and good news. :-)

Unfortunately, TeX Live 2021 still has this bug. I tested version 20210325 
(which is the latest on the historic TeX Live FTP site), with subversion 
tag texlive-2021.3 (which is the latest tag in the TeX Live repo).

The good news is that I found a simple workaround: use pdftex instead of 
luatex to build the affected packages. I am currently building all packages 
matching ‘^texlive’ a few times to find the ones needing this workaround.
So far, I found these:

• texlive-amsfonts
• texlive-amscls
• texlive-babel
• texlive-babel-swedish
• texlive-latex-amsmath
• texlive-generic-babel-english
• texlive-latex-cyrillic
• texlive-latex-graphics
• texlive-latex-tools

I will submit a patch to the guix-patches mailing list (with this bug in 
Cc:) as soon as the process finishes.

FWIW I managed to get a Valgrind report for TeX Live on core-updates,

using ‘--extra-debuginfo-path’ to help it a bit:

Not that it helps a whole lot yet!

Thank you for the report, I will check asap.

Unfortunately I’m still having problems with glibc debug info and thus

Valgrind doesn’t work for me.

When I use this command:

$ guix environment texlive-amscls --pure \

--with-debug-info=texlive-bin \

--ad-hoc valgrind glibc:debug gdb

I get luatex linked with this glibc:

$ /bin/which luatex

/gnu/store/s44lh4hqbklplqm3cpaih3rxsv8i1dx1-profile/bin/luatex

$ ldd /gnu/store/s44lh4hqbklplqm3cpaih3rxsv8i1dx1-profile/bin/luatex | grep libc.so

libc.so.6 => /gnu/store/rhlm1nixi98x09xbyjc4i38gl9xs01f2-glibc-2.33/lib/libc.so.6 (0x00007fec0ac3d000)

But for some reason I get debug info for a different glibc:

$ ls -1 /gnu/store/s44lh4hqbklplqm3cpaih3rxsv8i1dx1-profile/lib/debug/gnu/store/

5ahv6zfv64jm5y7sficll0k2scr7cxvz-glibc-2.33

I saw it, but after I posted my message above. Thank you!

I will use your command line to get a Valgrind report for TeX Live 2021 and post it to the dev-luatex mailing list as well.

Yes, you need debug info for (@@ (gnu packages commencement)

glibc-final), which is not what you get when you type “glibc:debug”.

HTH!

Thanks! I was able to run Valgrind on LuaTeX 1.13.0, which is the latest 
one in TeX Live 2021.

The invalid reads and writes don’t happen on every run. I had to re-run the 
command 3 or 4 times until I got the result below (which matches our 
experience with the build failures in Guix packages)

Thanks,
Thiago

valgrind: m_mallocfree.c:303 (get_bszB_as_is): Assertion 'bszB_lo == bszB_hi' failed.
valgrind: Heap block lo/hi size mismatch: lo = 1248, hi = 102.
This is probably caused by your program erroneously writing past the
end of a heap block and corrupting heap metadata.  If you fix any
invalid writes reported by Memcheck, this assertion failure will
probably go away.  Please try that before reporting this as a bug.

It did, thanks for the tip! For the record, this is the command line that

worked for me:

$ guix environment texlive-amscls --pure \

--with-debug-info=texlive-bin \

--ad-hoc \

-e '(list (@@ (gnu packages commencement) glibc-final) “debug”)’ \

valgrind gdb

Then I pointed valgrind at the /lib/debug directory in the environment’s

profile, as seen in my previous message.

[PATCH core-updates] build-system/texlive: Change default format to pdftex

Recipients:(address . 48064@debbugs.gnu.org)(name . Thiago Jung Bauermann)(address . bauermann@kolabnow.com)

Message-ID:20210702160010.246888-1-bauermann@kolabnow.com

LuaTeX has a bug where sometimes it corrupts the heap and aborts. This

causes the build of texlive packages to fail at random. The problem is

being tracked at https://issues.guix.gnu.org/48064.

While a fix isn't found, switch the default TeX format (and consequently

also the engine) to pdftex to avoid the issue.

* guix/build-system/texlive.scm (texlive-build): Change default value of

the ‘tex-format’ key parameter to “pdftex”.

Hello,

Originally I had a bigger patch which changed packages individually to

build with pdfTeX, because I thought the bug in LuaTeX was triggered only

by specific packages. As I changed more and more packages though, I

realized that any package can trigger the problem and the heap corruption

happens at random.

Therefore, to work around the LuaTeX bug we need to build all packages with

pdfTeX. I tested the patch with this script:

Toggle snippet (38 lines)

#!/bin/bash

set -e

LOG_FILE="$1"

ROUNDS=$2

function verify_package() {

local package="$1"

local log_file="$2"

if ! guix build "$package"; then

echo "failure while building $package" >> "$log_file"

return

echo "success while building $package" >> "$log_file"

if ! guix build --check --rounds=$ROUNDS "$package"; then

echo "failure while checking $package" >> "$log_file"

return

echo "success while checking $package" >> "$log_file"

return

}

guix describe >> "$LOG_FILE"

echo rounds = "$ROUNDS" >> "$LOG_FILE"

echo >> "$LOG_FILE"

for package in $(guix package --list-available='^texlive' | cut -f1)

verify_package $package "$LOG_FILE"

done

and called it with `./verify-texlive-packages.sh verify-packages.log 5`.

I see some packages fail during `guix build --check` because they don't

build deterministically for some reason (which is a separate problem), but

I don't see any package failing to build anymore.

Bah. Still, if you have the whole texlive upgrade, we should apply it!

We haven’t heard from dev-luatex yet. I think we should go with this

workaround for now (those build failures are frequently preventing

evaluations at https://ci.guix.gnu.org/jobset/core-updates from

completing, which is a real bummer). Does using ‘pdftex’ rather than

‘luatex’ have an impact on the output of these packages?

Thanks!

Pushed as 04f9f9158da348e8299e9ab90ec389ba81be46b0 with the text above

inlined as a FIXME comment.

On IRC there were concerns about Unicode support, which LuaTeX provides

but pdftex doesn’t (IIUC), but it would seem that the worst that can

happen is that documentation of the packages themselves would be

mangled, which is okay.

Anyway, it’d be ideal to get feedback from the LuaTeX folks!

Thanks,

I chose pdfTeX for the workaround because it’s the direct “predecessor” to

LuaTeX, so I thought it would behave most similarly to it. But it’s just an

uneducated guess.

Searching around a bit¹²³, XeTeX also has native Unicode support, so we

could also switch to it. Either as the default, or for specific packages

that need it.

NB: I last used TeX more than 15 years ago, and even then just lightly and

sporadically. Don’t trust my judgement on TeX-related issues. :-)

Agreed!
