SYMPTOMS
If you turn on optimizations before you compile code (typically in release mode), Visual C++ 6.0 Optimizer may generate code that causes an access violation when it is executed. The same code works as expected if you turn off optimizations before you compile the code, or if you compile the code by using Visual C++ 7.0 and you turn on optimizations.
