aarch64 Fedora Rawhide 3.9:
https://buildbot.python.org/all/#/builders/245/builds/445

It seems like the "ldconfig" command crashed (signal 11: SIGSEGV).

ldconfig is used by _findSoname_ldconfig() of ctypes.util which runs the "/sbin/ldconfig -p" command with LC_ALL=C and LANG=C env vars.

It looks like a Fedora issue rather than a Python bug.
