["Ludovic Courtès" <ludo@gnu.org>]

Hello,

This command fails:

  guix pull -s i686-linux \
    --commit=13b905bf28ec6309043bd61c5a92744b13352021 \
    -p /tmp/test

‘guix-packages-base.drv’ fails to build due to a Guile segfault (!):

I wonder when it started failing, but it may have been pre-core-updates
merge.

Ricardo, do you have a known-good commit?

<https://ci.guix.gnu.org/jobset/guix?border-high=53879> suggests it
passes 25% of the time.

Thanks,
Ludo’.
