Crash in RemapProcessor::perform_remap
--------------------------------------

                 Key: TS-221
                 URL: https://issues.apache.org/jira/browse/TS-221
             Project: Traffic Server
          Issue Type: Bug
            Reporter: Leif Hedstrom
            Priority: Critical
             Fix For: 2.1.0, 2.0.0a


In trunk, and sometimes on 2.0.x branch (not as frequent, cause it crashes in 
another place), I get this crasher:
