[Dr Andrew Perella]

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;

}

}
