A bug like that is more urgent than memory corruption issues IMO.  Blaming the 
compiler is the last thing anyone wants to do, so it's a bug likely to cause 
hours of frustration for anyone who encounters it.

As an idea of how to temporarily fix it, could you disable the optimization that 
forces unsigned comparisons in the loop?  That seems like a very small 
optimization we could afford to lose until you can fix this properly.
