[drlvm][jit]drlvm crashes when running dacapo.bloat into the 6th iteration.
---------------------------------------------------------------------------

                 Key: HARMONY-4136
                 URL: https://issues.apache.org/jira/browse/HARMONY-4136
             Project: Harmony
          Issue Type: Bug
         Environment: Win32, release version, server mode
            Reporter: Qi Ji


Run dacapo bloat benchmark at server mode by this command line:
java -server -cp . Harness -n 10 -s large bloat
The vm crashes at the 6th iteration:

** Exception while optimizing finalizeVisit(LEDU/purdue/cs/bloat/trans/SSAPRE$ExprInfo;LEDU/purdue/cs/bloat/cfg/B
DU/purdue/cs/bloat/trans/SSAPRE$Def;)V of class EDU/purdue/cs/bloat/trans/SSAPRE

The vm also crashes in the 6th iteration with the same exception if I use such command line:
java -server -XX:vm.dlls=gc_cc.dll -cp . Harness -n 10 -s large bloat


But it's ok to run dacapo.bloat at jit mode.
