So, my question remains: would it be enough to modify g_error? g_mem_set_vtable() allows you to replace the guts of g_malloc. Then you can determine what happens when malloc() returns NULL before GLib calls g_error(). If you can find sufficient memory by freeing caches or whatever and actually allocate the requested memory, then you can avoid aborting. Note that in your malloc handler you can't call any GTK+/GDK/Pango/etc. functions. Regards, Owen
