Subject: faulthandler: don't use sigprocmask()
X-Git-Tag: v3.3.0a1~2552
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=cf2a807831ee93ef39e73fcc682894b0695b6143;p=thirdparty%2FPython%2Fcpython.git

faulthandler: don't use sigprocmask()

It has an undefined behaviour with threads, only use pthread_sigmask() if
it is available (and not broken).
