          Issue ID: 13722
           Summary: onFinalizeError should not allocate
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: druntime
          Assignee: nobody@puremagic.com
          Reporter: thecybershadow@gmail.com

As our GC is non-reentrant, allocating during a GC run (when invoked by the GC for finalization) is invalid. Thus, onFinalizeError should use the same pattern as onOutOfMemoryError to avoid allocating memory.
