问题
Somewhere in a mass of code that I did not write (but I am trying to debug), an assertion fails in the GLib library:
(process:31987): GLib-CRITICAL **: g_hash_table_lookup: assertion `hash_table != NULL' failed
However, GDB and the code keeps on going. I would like GDB to break where this assertion fails so that I can find out why it is failing. I am not given any more information about where this assertion is. Is there a way to get GDB to break on such a failure?
回答1:
Break on g_log(). This covers all cases like g_warning(), g_critical(), etc.
回答2:
You should add an environment variable like this:
G_DEBUG=fatal_warnings gdb ...
