[jira] [Resolved] (DAFFODIL-2283) ATO and HL7 saved parsers fail with Stack Overflow errors during generation on commit 7e8e1b3e

     [ https://issues.apache.org/jira/browse/DAFFODIL-2283?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mike Beckerle resolved DAFFODIL-2283.
-------------------------------------
    Fix Version/s: 2.6.0
       Resolution: Fixed

My understanding is that increasing stack size to 4M solves this problem.

There is a general issue with stack depth being very deep and unpredictably so, But daffodil has a compiler, and using up .4% of a gigabyte  (4 Megabytes) for stack to avoid this problem is clearly the right way to fix it rather than worrying about depth of recursion.
