Subject: bug#40315: Graft segmentation faults

[Message part 1 (text/plain, inline)]

Hey,

With recent Guix revisions ([3] for example) I've had some apparently
random segmentation faults with grafts. I've encountered this on two
machines, both times it appears not to happen repeatably, as re-running
the graft can work. I encountered this when running guix package -u, and
running it again eventually worked.

One of the logs mentioned not being able to allocate memory. The machine
this was running on has 16GB of RAM, plus 16GB of swap, and most of the
memory was free, so I think using all of this is unlikely.
