I've posted a proposal to provide an interface for allocating stacks
in glibc:
Misc: Add <sys/cstack.h> and the cstack_* family of functions
<https://sourceware.org/pipermail/libc-alpha/2021-May/126608.html>
This is based on our observation that many applications use static
buffers for alternate stacks, which is not thread-safe.
I'd appreciate If you could comment here or on libc-alpha based on your
experience with alternate signal stacks.
Thanks,
Florian
