There were two of these right in a row, and none with quite the same failure mode before today, so this looks like a possible 1.16 regression to me, possibly related to #41014.

It looks like the underlying problem here is that testprog TimeProf (the binary TestTimePprof runs) timed out. The "failed to fetch any source profiles" is a follow-on failure because the binary didn't exit. There's not much information about the time-out, unfortunately. We may want to add in a GOTRACEBACK=crash just to get more details.
