[Bug c++/29871] New: Allocating 8Mb structure on the stack causes segmentation fault in output program

["angus at uducat dot com" <gcc-bugzilla at gcc dot gnu dot org>]

If the following tiny program is built, the resulting executable will seg fault
upon the construction of a.

class a {
public:
        a() {}
        ~a() {}
        char c[(8*1024*1024)];
};

int main(void) {
        a _a;
    return 0;
}

I've got this to occur in Suse Enterprise 10 32-bit, but got similar results in
open Suse 10.1 64-bit.
