Ouch, that’s new, isn’t it?

Could you dig when these failures started appearing?

Seems it didn’t happen on ci.guix at:

  https://ci.guix.gnu.org/jobset/master
  https://ci.guix.gnu.org/jobset/guix

This reminds me of the other GC marker bug you reported.  Is there
anything that could lead to different behaviors?

Thanks,
Ludo’.
