How can I find out where is my code causing GLib-GObject-CRITICAL?

When a C/C++ application fails with the following CRITICAL, can you please tell me how can I find out where is the code causing the error?

I have tried to run it in the debugger, trying to do a 'bt when the program fails. But it does not show where is the code causing the CRITICAL:

(process:3155): GLib-GObject-CRITICAL **: /build/buildd/glib2.0-2.22.3/gobject/gtype.c:2458: initialization assertion failed, use IA__g_type_init() prior to this function

You can break on g_log and then do a backtrace from there.

You should pass --g-fatal-warnings to your application when you run it inside gdb.

I think it does show where it is causing the problem (deeper in the stack trace):
