I get exactly the same objmap.c crash as you in an application I have
written using SIP (but not PyQT).
The crash is timing related - depending on when the garbage collector is
called, the sip hashmap still has a reference sometimes to a freed python
wrapper.
I will investigate further.
Cheers,
Andrew
P.S. I made the same "fix" you did to objmap.c:
while (w != NULL)
{
/* We are removing it from the map here. */
sipSetNotInMap(w);
sip_api_common_dtor(w);
w = w->next;
//extra code "fix" here
if (w==0xdbdbdbdb)
{
printf("WARNING: SIP would normally crash - would try to access freed
memory\n");
w=NULL;
}
}
