This boils down essentially to two problems at once: Both gcc7 and gcc10
libstdc++.so and libgcc_s.so are loaded, which breaks exception handling.
Massaging dyn:runpath and preloading then uncovers the second problem:

ro sunts /tmp # ./mate-system-monitor

(<unknown>:11878): glibmm-CRITICAL **: 14:08:27.008:
unhandled exception (type Glib::Error) in signal handler:
domain: g-io-error-quark
code  : 0
what  : Unable to find default local file monitor type

Segmentation fault


That's what I already wrote in the thread
<https://www.mail-archive.com/openindiana-discuss@openindiana.org/msg26671.html>

The /usr/lib/gio/modules/ directory has the giomodule.cache file.
When you try to recreate it with gio-querymodules /usr/lib/gio/modules/,
it's gone!

So probably the right fixes should be: Sort out the gcc7/10 confusion,
and compile glib with inotify/fam support.
