          Issue ID: 21117
           Summary: When compiler segfaults running autotester, cannot
                    tell which file it was testing
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: bugzilla at digitalmars.com

Here's the relevant part of the log file generated by circleci. Since each test
file is run in a separate thread, there's no way to tell which file resulted in
the compiler seg fault.
