Dynamically allocate the alternate signal stack #10266

merged 3 commits into from Mar 5, 2021

  1. Dynamically allocate the alternate signal stack 

    In Glibc 2.34 and later, SIGSTKSZ may not be a compile-time constant.
It is no longer possible to statically allocate the alternate signal
stack for the main thread, as we've been doing for the last 25 years.

This commit implements dynamic allocation of the alternate signal stack
even for the main thread.  It reuses the code already in place to allocate
the alternate signal stack for other threads.

Fixes: ocaml#10250.
