Re: [PATCH] posix_spawn: use a larger min stack for -fstack-check [BZ #21253]

Depending on what constant page size GCC uses, this will not fix the -fstack-check bug on all architectures.
I doubt there is a good solution to this, except fixing the GCC bugs in this area and allocating an additional page in glibc. 

Thanks,
