On current Fedora 39, "__run_test_gui__" would hang octave with 100%
reproducibility. I observed that on AMD FX-8350, i9-9880H, and on Raspberry PI
4 (aarch64). The desktop has to be GNOME, the
run completes w/o problem on GTK. The run also completes fine if I started GUI
with "--experimental-terminal-widget". 
This happens with both octave 8.4.0 (as supplied by Fedora repo) and with
self-compiled 9.0.91 (with different compilers and compilation flags including
-O0).

When octave started from Gnome terminal as "octave --gui" the octave's
CommandWindow is flooded with 


 (octave-gui:68826): GLib-GIO-CRITICAL **: 20:21:28.119: file
../gio/gfileinfo.c: line 1766 (g_file_info_get_icon): should not be reached

warnings. They are continue to pop-up in large numbers during the
"__run_test_suite__" execution. After a short time octave GUI becomes frozen
and non-responsive (see attached screenshot "hang2.png"). GUI hangs at/after
execution of oct-inttypes.cc-tst, yet fntests.log indicates that there are few
more test have finished (see attached fntests.log). The number of those
"extra' tests varies, whne compiled with "-O2" it finishes only one more test
(Cell.cc-tst).

I have run "strace octave --gui 2> str2.log; str2log.gz is attached. 
I have also tried to attach gdb to a frozen octave process. Here is what I see
there:

 26      __wait4_time64 (pid_t pid, int *stat_loc, int options, struct
__rusage64 *usage)
27      {
28      #ifdef __NR_wait4
29      # if __KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64
30        return SYSCALL_CANCEL (wait4, pid, stat_loc, options, usage);
31      # else
32        pid_t ret;
33        struct __rusage32 usage32;
34
(gdb) thread apply all bt
