I forgot to say what it does - it adds «lib/gcc» to the CPATH so that we don't get errors like «ld: cannot find crtbeginS.o: No such file or directory».

I think this has no effect because this ‘native-search-paths’ is already
inherited from ‘gcc-9’, which ‘libgccjit’ inherits from.

Can you confirm?

From a discussion on IRC, this has to do with the fact that libgccjit
needs all these search paths defined at run time.

Thanks,
Ludo’.

Nope, it does have an effect. I added "lib/gcc" to the original paths (and that was the needed thing).

(sending again because I forgot about the debbugs e-mail)

In that case, could you (1) arrange to write the search path in a way
that reuses (package-native-search-paths gcc-9), and (2) add a comment
explaining why “lib/gcc” is needed (it looks unusual)?

Thanks in advance,
Ludo’.

Perhaps the original issue is the one reported/fix with a patch here [0]
? Formbi, could you share a simple reproducer so that we can test if
the patches resolve it? It seems it'd be useful to upstream as well (to
have a reproducer).

Thanks!

Another data point: this seems to be worked around in Nix using the fix
proposed by Formbi:
