I have a GMainLoop that I want to run in its own thread. But I seem to b
doing something horribly wrong with the event source I'm trying to
attach to it (all as part of the same thread). My thread function
includes this code:
GMainContext * main_context = g_main_context_new();
GMainLoop * main_loop = g_main_loop_new(main_context, false);
GSource * quit = g_idle_source_new();
g_source_set_callback(quit,
::openvrml_player_command_channel_loop_quit_event,
main_loop,
notify);
guint source_id = g_source_attach(quit, main_context);
g_assert(source_id != 0);
g_main_loop_run(main_loop);
g_source_unref(quit);
g_main_loop_unref(main_loop);
g_main_context_unref(main_context);
If I do not attach the event source, the code runs. But if I do attach
it, as above, I crash as soon as I start to run the main loop:
#0 0x0000000000000000 in ?? ()
#1 0x0000003c9242cf6a in g_main_context_dispatch () from

#9 0x0000003c8f4cd62d in clone () from /lib64/libc.so.6
#10 0x0000000000000000 in ?? ()
I figure I'm probably missing something about the proper way to attach
the event source, perhaps related to the fact that I'm not doing this in
the main thread.
