Considering that the functions work in some cases and not in others, it's  
probably a corruption issue.

All I can say is, try to isolate *when* the corruption occurs.  What I'd  
recommend is printing the contents of the typeinfo at the beginning of the  
program, then examine them after the corruption.  See if you can spot a  
difference.  I've done things like start a thread that continuously  
monitors a specific memory location to see if it ever changes, and then  
break on that check.  Then look at the main thread to see what it is doing.

These bugs suck, sorry you got one.
