STINNER Victor <vstin...@python.org> added the comment:

On my x86-64 Fedora 35 with the CPU "Intel(R) Core(TM) i7-6820HQ CPU @ 
2.70GHz", I get:

* SIGSTKSZ = 8192
* getauxval(AT_MINSIGSTKSZ) = 2032
* faulthandler stack.ss_size = 10224
* os.sysconf('SC_MINSIGSTKSZ') = 2032

In C, sysconf(_SC_MINSIGSTKSZ) is similar to getauxval(AT_MINSIGSTKSZ), but the 
glibc sysconf(_SC_MINSIGSTKSZ) is more generic, whereas IMO 
getauxval(AT_MINSIGSTKSZ) is more the low-level Linux API.
