Hi,

While working to improve my reports on https://gitlab.gnome.org/GNOME/mutter/issues/18, 19 and 31, I've tried to run gnome-shell under valgrind.


Jonas Ådahl's suggestion in https://gitlab.gnome.org/GNOME/mutter/issues/31#note_56382 was good, and I've successfully reached a (quick but permanent) crash situation, even when running in non-hybrid GPU mode.

I've written a rather liberal suppressions file in order to ignore every writes made to memory mapped from the i965 GPU (attached here, fwiw)

The crash location is very reliably in "st_theme_get_custom_stylesheets (st-theme.c:311)" as called from Javascript code — unfortunately dump_gjs_stack_on_signal_handler() dies trying to report the JS stack.

It seems that st_theme_get_custom_stylesheets() at https://gitlab.gnome.org/GNOME/gnome-shell/blob/master/src/st/st-theme.c#L311 is attempting to check the type of an object which has already been allocated and de-allocated (the actual place of allocation/deallocation varies from run to run, but here are a few samples). Upon closer inspection, it actually looks like the themes->stylesheets g_hash_table's nodes got overwritten at some point.

My question is, what is the best course of action here?

 * non-trivially fixable valgrind false positive ⇒ drop?
 * mutter issue ⇒ report in the mutter project?
 * gnome-shell issue ⇒ report in the gnome-shell issue?

(my goal is to attempt to get meaningful clues to #18, #19 and possibly #31 in order to help with the search for a solution)

Thanks in advance!
