--- Comment #4 from David Malcolm <dmalcolm at gcc dot gnu.org> --- <TemptorSent> Also, I'm not sure if it's available, but if we could print the parent process and commandline passed at the beginning of an error report, and tag the output for the error report with the PIDs, it would make tracking things in parallel builds much easier.
