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

             Summary: Crash in transformations
                 Key: TS-2820
                 URL: https://issues.apache.org/jira/browse/TS-2820
             Project: Traffic Server
          Issue Type: Bug
          Components: Core
            Reporter: Brian Geffon


I'm seeing an easy to reproduce crash in 4.2.0 and master (5.0.0), so I'm assuming it was introduced between 3.2.x and 4.1.0. To reproduce I'm using a simple null transformation plugin and just making repeated curl requests.
