The test itself seems to always run in /tmp, which is tmpfs in my case. I tried
patching it to run in /var/tmp, which is ext4 (on LVM), but that failed as well.

I could reproduce the issue even outside of the guix build process.
I downloaded the tarball, extracted it and ran configure + make + make check.
The latest git version worked fine, even though the asserts in test_option_b.c
didn't change.

I built it once and it passed (note that it failed *everytime* I
wanted to build it).
Maybe a dumb question, but how do I force a rebuild of an already
built package?:)
