AFAIK, the channel used for emitting diagnostic from codegen threads is not guaranteed to be fully drained when compilation session is aborted. |

@Amanieu I left this open in the case there is an interest in fixing the underlying cause, if not feel free to close. |

The srcloc.rs test has seen a couple sporadic failures on CI with the
x86_64-gnu-noptjob.The error is that it is not always emitting all 23 errors. Sometimes I see it report anywhere from 3 to 15 errors.
I'm able to reproduce locally with
rust.optimize-tests = false, and running in a loop. The failure rate isn't high, but I can repro within a few seconds.cc @Amanieu
