And perhaps we should think a little bit about maintainability. I was
never very impressed by the idea of the red zone anyway, but how shall
we make sure that this problem does not recur? I don't want to force
inline asm to disable the red zone, and all we need is some way to
warn the programmer that there's a problem. But without parsing the
assembly code I'm not sure how to do that. We could have a warning
about the red zone. This warning would disappear if the programmer
annotated the function as "red zone clean" or somesuch.
