IMO they should make -d2SSAOptimizerUndefinedIntOverflow- a permanent option (i.e. not a hidden flag). I also think they should automatically enable it (that is, disable the optimizations) if the /sdl option is passed to the compiler (I'll accept this instead of making it a permanent flag). The logic being that you really don't care about the performance if you're using /sdl to begin with and would rather it just generate safer secure code. Edit: Also keep in mind that to disable these optimizations the complete flag is "-d2SSAOptimizerUndefinedIntOverflow-" minus quotations. That is it includes the dash/minus at the end to disable it.
