Optimized MSVC builds also restore the stack and frame pointers. But
before that it tries to pop local registers saved on the stack. Bingo!
My guess (but I've not compiled un-optimized to test it) is that
non-optimized MSVC builds work because the compiler is reloading
variables and/or being much less aggresive in caching values on
registers.
