Hmmm ... what's your settings in Bochs/VMware? Memory/CPU usw?
other hints:
Do you set all relevant pointers in your queues to NULL?
Do you set your first element for a search_query to queue->start instead of queue->start->next? (provided you use this approach for linked list management) And yes, it *IS* important!
Do you end a search query with (element==NULL) or with (element->next==NULL)? Maybe you just don't get the last element - which is the crucial one - and get a null pointer?
Do you query for NULL pointers after malloc/realloc?
Do you test a pointer for NULL *before* you test an attribute of it? (thx to solar for this one)
stay safe.
