bug#66610: Acknowledgement (potrace, po4a; guix bug, complete console output)

[Olav Smorholm <olavks@gmail.com>]

This may be relevant dmesg, where all should be from guix bootstrap on
gentoo-musl hardened after garbage collecting, guix pull and update.
I have enabled unsafe(rnd) kernel options security and hardening options.
So the bug may have revealed itself here. A few of these lines are
suspicious, and xsltproc may coincide, and tripped by kernel not safe
for bugs.
xsltproc[29510]: segfault at 7fffff7fefe0 ip 00007ffff7b952ce sp 00007fffff7fefb0 error 6 in libc.so.6
Below this is a refresh of guix pull and update.
