The compiler can ensure that you hit at least every 4k or so.
And it already does.
Doesn't look so:
int bar(int a) {
int[8000] b = void;
b[$-1] = a;
return b[$-1];
}
On Win32:

leave

It doesn't do it on Linux because gcc doesn't do it. But the
capability is in the back end, and it does it for alloca(), too.
Hmm... but this using DMD, not GDC. Or do you mean that DMD
doesn't do it, because GCC doesn't do it either? If so, what is
the reason for this? Why shouldn't this feature be enabled on
every platform?
