[jira] [Updated] (TS-798) traffic_server crash if add non-existent plugin in remap rule

["Leif Hedstrom (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/TS-798?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Leif Hedstrom updated TS-798:
-----------------------------

    Fix Version/s: 3.0.0
         Assignee: Leif Hedstrom

This is actually a more serious problem that it seems, in "error" cases, we actually end up adding broken mapping entries to the lookup tables, and then we free them.
