Conversation
faulthandler now allocates a dedicated stack of SIGSTKSZ*2 bytes, instead of just SIGSTKSZ bytes. Calling the previous signal handler in faulthandler signal handler uses more than SIGSTKSZ bytes of stack memory on some platforms. (cherry picked from commit ac827ed) Co-authored-by: Victor Stinner <vstinner@redhat.com>
