#!watchflakes
post <- pkg == "runtime/pprof" && `signal: segmentation fault`

From a SlowBot on https://go.dev/cl/428716 (https://storage.googleapis.com/go-build-log/38af0500/linux-amd64-longtest_88ed84a0.log):

signal: segmentation fault (core dumped)
FAIL	runtime/pprof	48.544s

There is also one of these in a very recent dashboard log:
greplogs -l -e 'signal: segmentation fault .*\nFAIL\s+runtime/pprof' --since=2022-01-01

Marking as release-blocker at least until we can determine whether this is a Go 1.20 regression.
