          Issue ID: 13723
           Summary: onFinalizeError should not be called for Errors
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: druntime
          Assignee: nobody@puremagic.com
          Reporter: thecybershadow@gmail.com

onFinalizeError will currently catch any Throwable and replace it with a FinalizeError. If the Throwable was an Error, however, this is redundant, and only serves to mask the real source of problems (e.g. an InvalidMemoryOperationError).
