onErrorStackTrace

Invokes gdb, which attaches to the current process and shows a stack trace. Called by glib.global.onErrorQuery when the "Stack trace" option is selected. You can get the current process's program name with glib.global.getPrgname, assuming that you have called gtk.global.init_ or gdk.global.init_.

This function may cause different actions on non-UNIX platforms.

When running on Windows, this function is not called by glib.global.onErrorQuery. If called directly, it will raise an exception, which will crash the program. If the G_DEBUGGER environment variable is set, a debugger will be invoked to attach and handle that exception (see Running GLib Applications).
