[Ludovic Courtès]

Hello,

This command fails:

‘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’.
