guix gc and the reconfigure again (now with 
373c7b5791acd8f377455be47260948b843dd5db) still results in the same error. 
Of course, if the miscompilation was in something that couldn't get 
collected… However, I have been able to reproduce it on that one VM across 
multiple Guix commits.

Best,
Jack
