gtkmediastream.c:103: pointer index expression... overflowed...
Running gnome-software with built gtk4 with address sanitizer flags on (see the description of the #6467 (moved)), I've got a below crash. It happened when I've been changing between different source types of a GCompris application and then closed the window. This is still the sources in commit c93fa922 .
../subprojects/gtk/gtk/gtkmediastream.c:103:1: runtime error: pointer index expression with base 0xffffffffffffffff overflowed to 0x000000000027
../subprojects/gtk/gtk/gtkmediastream.h:33:1: runtime error: member access within misaligned address 0xffffffffffffffff for type 'struct GTypeInstance', which requires 8 byte alignment
0xffffffffffffffff: note: pointer points here
