Sometimes those C optimizations don't really help... It's far more likely that your optimizer found a bug in your code than you found a bug in the optimizer. The problem with compilers is that they do exactly what you ask them too bad women and children won't follow that example Steve -- Stephen J.

The compiler did what it was supposed to do: if you were calling a function that had no side effects, it knew that it could eliminate the call without having any effect on correct operation. It was right. Benchmarking is a known science; calling your operation in a way that insists on a side effect (as I'm sure you found) lets you get the effect you want. Steve -- Stephen J.
