I try to run emacs in gdb with debug symbols for some libs available, I
succeed with gtk+, but it doesn't work for glib and glibc. It looks
strange to me, but maybe I am doing something wrong.
Reproducer:
guix shell gdb emacs-next-pgtk glibc:debug gtk+:debug glib:debug \
--with-debug-info=glibc --with-debug-info=glib --with-debug-info=gtk+ \
--no-grafts -- gdb .emacs-30.0.50-real

At least for glibc, the glibc that is linked against is the one in (gnu
packages commencement), which is hidden from the user. The one in (gnu
packages base), which you can refer to with "glibc" is different. You
can try to find the proper debug output by looking at `guix size` of
your store path, then finding out the deriver for glibc with `guix gc
--derivers` and finally looking at the .drv to find out what the debug
output should be.
For glib, it might be similar, make sure that you're using exactly the
right store path for it.
Best,

Perhaps try on the core-updates branch, where glibc no longer has its
symbols stripped. Another thing that can cause the debug symbols to not
be found is grafts, as described in #48907, so when debugging I'd
recommend using --no-grafts for now.

Thank you for the tips.
For future readers: the core-updates merged, it should be fixed, however,
I didn't check if it works now.
Closing the issue, but feel free to reopen.
