[drlvm][signals] Crash handler may infinitely loop on Linux x86_64
------------------------------------------------------------------

                 Key: HARMONY-4952
                 URL: https://issues.apache.org/jira/browse/HARMONY-4952
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Gregory Shimansky
            Priority: Minor


Sometimes crash handler may crash itself on trying to display fault information. I've got
this on gc.ThreadSuspension in interpreter mode:
