Hello,
Building ‘guile3.0-guix’ on x86_64-linux from Guix commit
1a30351bf37930222f077cdbcbb6659372f1ea2d leads to a GC segfault. This
can be reproduced with:
guix pull --commit=1a30351bf37930222f077cdbcbb6659372f1ea2d
guix build -K guile3.0-guix
‘guix pull’ also segfaults similarly on x86_64-linux.
The build log for ‘guile3.0-guix’ goes like this:
