Once upon a time I had to figure out an issue where I forgot a `return` statement at the end of a non-`void` function, so the C++ compiler happily omitted both RETs for some reason and let the program go straight into illegal instructions. That was fun to debug (not fun, I practically had to single-step through the entire program) because every time this happened the debugger was incredibly confused about what the fuck was going on and nothing made any sense.
