Still, this looks like some interference from the environment. When I
ran `su $username` first, there was no error. I ran `set` before and
after `su` and diffed the results. The only suspicious thing I found
was:

   --- nosuset   2022-02-03 14:46:16.691231539 +0100
   +++ suset     2022-02-03 14:45:51.658607639 +0100

   -LD_PRELOAD=/gnu/store/s53sv4740vkaqzn3m2zvvnpy26hg2925-spectrwm-wz-3.2.0/lib/libswmhack.so.0.0

It’s related to the window manager, which is related to Xorg, and the
LIBC error pertains to X libraries. Could there be a connection here?

Sure enough, unsetting LD_PRELOAD seems to fix things, too.

From spectrwm man page:

   Note that workspace mapping is handled via libswmhack.so. When
   autorun spawns windows via a daemon, ensure the daemon is started
   with the correct LD_PRELOAD in its environment.

   For example, starting urxvtd(1) via xinit(1):

   LD_PRELOAD=/usr/lib/libswmhack.so.0.0 urxvtd -q -o -f

   Spawned programs automatically have LD_PRELOAD set when executed.

I guess I need to alias guix to "unset LD_PRELOAD; guix" until I find
some more elegant solution.
