Changes in the layout of code or the stack. In particular, if you have bugs involving uninitialized variables or stack smashers, the behavior may change if such layout changes.
If you haven't already, run the static analyzer (Build and Analyze) on your code. Also, turn on as many compiler warnings as are useful and fix them. Note that some warnings require that optimizations be turned on to be effective, because they rely on data-flow analysis and the like that's only performed during optimization.
Good luck,
Ken
