I'm trying to build an installation binary for powerpc-linux and I came
across a segfault while building the store-database. Not a lot of data
to include from what I could gather.

working from commit 18393fcdddf5c3d834fa89ebf5f3925fc5b166ed
command was:
guix pack -C xz --fallback --system=powerpc-linux --localstatedir \
--profile-name=current-guix guix --without-tests=guix --no-grafts

This happened on real hardware and when using qemu emulation.
strace output attached

from dmesg (on ibook g4):
