Subject: tmp.perf/core segfaulting on metrics test

While trying to get back at processing patches for Linux 6.2, what I
have at tmp.perf/core branch is failing like below, can someone try to
help in diagnosing this?

People really should try to run 'perf test' before pushing things
upstream, but maybe this is related to a recent merge with
torvalds/master, I'll check, but as a heads up and if someone wants to
help...
