           Summary: Crash during printing anonymous union with writeln
                    family functions.

           Version: D2
          Platform: x86

            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos

writeln is not aware of anonymous unions inside of structs (probably classes
too).

The attached file crashes when run.

Thank you for improving writeln.

Maybe the string tag "union" is better than "overlap":
