Hi,

Does somebody know why nptl implementation does that ?

I have read https://bugzilla.redhat.com/show_bug.cgi?id=435337 and I doesn't agree.

There no way for the programmer to know the real size of the stack. Even if we know that the guard size is in the stack, we don't know the size used by tls (or internal nptl usage) at the begining of the stack. And this can be big : several KB.
