runtime/pprof: "signal" test failures

[mdempsky]

runtime/pprof is failing with unhelpful "signal: blah" error messages on a lot of builders. For some reason we're not getting any further details though. E.g., which runtime/pprof test is failing or a sigpanic stack trace.

The message is the exit status being reported by the go command. The test binary seems to be exiting due to the signal, without handling it itself.

Are there more recent instances of this?

All of the Google search results for site:build.golang.org "signal: segmentation fault" appear to be from April. Looks like this isn't a problem anymore.
