---------------------------------

             Summary: Segfault when trying to return an error from (remap) plugin
                 Key: TS-1978
                 URL: https://issues.apache.org/jira/browse/TS-1978
             Project: Traffic Server
          Issue Type: Bug
          Components: HTTP
            Reporter: Leif Hedstrom


The problem is that with the changes in 962d864851332858a202f8c14a9ec671ec4e9a6c to make the body factory always used, remap plugins now try to generate error pages without a factory template specified.
