<mgedmin> I'm seeing very weird segfaults in glib
 in g_closure_invoke(), to be precise
 this is on ubuntu gnome 14.10 with their gnome3-staging ppa enabled, so who knows what got broken where
 but basically all the apps are segfaulting left and right when widgets lose focus
 the stack trace is this: https://gist.github.com/0c80f6e81d9dfc4a4fd7
 I have a core dump and I can poke around it with gdb
 and gdb tells me closure->marshal is 0x7fd4ba283040 <g_cclosure_marshal_VOID__BOOLEAN>
 and real_closure->meta_marshal is 0x7fd4ba27fb10 <g_type_class_meta_marshal>
 the segfault is here: https://github.com/GNOME/glib/blob/glib-2-42/gobject/gclosure.c#L768
 it's invoking a local variable 'marshal' which is "optimized out" in the stack trace's locals
