Hello Guix (sorry for the cross-post, and thanks Roel for the tip),

It's been a while, so i apologise for asking what are probably dumb
questions.

Quite a while ago i ran into this issue where (it might have been after
a system upgrade including libc and such, i'm using git Guix on Arch
Linux) all binaries segfault.  This is quite a while ago, so it would've
definitely been an older kernel version then, but i can't say which
one.  We're talking like 4 months ago.

I didn't really have time to look at it then, and now i'm trying to get
back on the Guix-horse.  I've done `guix package -i ..` for a few
packages, some of which have and some of which haven't been updated in
the meantime, but the problem persists.  Should i blow away the entire
/gnu/store and reinstall Guix from scratch, or can something be
debugged/salvaged?  My debugging-fu is weak, so i might need pointers.

I've taken Roel's suggestion and attached the output of `strace less`
which is one of the binaries that segfaults.

Hope this isn't too much PEBKAC for one afternoon!

Cheers,
p.
