Just curious, where did you find this? I googled a bit for the ABI requirements
but did not find very useful info yet.

Ok. What I find strange at the moment is that the stack seems to be
MAP_ALIGNED(pthread__stacksize_lg) in pthread_stackalloc, with
pthread__stacksize_lg set to 18 are there do not seem to be a problem with the
address returned by mmap.
