[jira] [Commented] (DAFFODIL-2189) Unparse with trace on causes Abort

["Michael Beckerle (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DAFFODIL-2189?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16894083#comment-16894083 ] 

Michael Beckerle commented on DAFFODIL-2189:
--------------------------------------------

We need some unit tests that run with trace on, so as to insure that the debugger/trace works for a round-trip test.  Otherwise it is too easy to break something that only fails under tracing/debug, but not notice.
