You'd probably have to reduce your code piece by piece until it starts acting 
the same in both cases and then try and determine the smallest example 
possible using that. Then it could become fairly clear whether it's a library 
bug or a compiler bug. But narrowing it down is likely to be rather unpleasant 
regardless.
