Yes. And without optimization enabled, I don't see any reason that the compiler should be expected to reuse the stack space; that's an optimization. The compiler might, for example, be able to generate code more quickly by using a new stack slot for every variable. Or, using different stack slots, might result in faster code on some machines, which is nice even at -O0.


If people find no other way to make it work other than -Os, that's fine.

I think -Os is an optimization for code size, not for stack size. It's not clear to me that reusing the stack slot will result in smaller code all the time on all machines.
