          Issue ID: 21042
           Summary: Darwin_64_64 fails autotester, but no clue in log file
                    when CFGalwaysframe is turned off
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Mac OS X
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: bugzilla digitalmars.com

The failure can be triggered by turning off CFGalwaysframe in
backend/backconfig.d.

Could it be this: "ld: warning: could not create compact unwind"?

The end of the log file is:
