[jira] [Created] (DAFFODIL-2572) Regression in schema compilation memory requirements

Steve Lawrence created DAFFODIL-2572:
----------------------------------------

             Summary: Regression in schema compilation memory requirements
                 Key: DAFFODIL-2572
                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2572
             Project: Daffodil
          Issue Type: Bug
          Components: Performance
            Reporter: Steve Lawrence


I have a fairly large schema that compiles successfully on 3.1.0 with 200MB of memory given to the JVM.

With the current main branch, I have to bump the memory up to 1300MB before it compiles, otherwise I get an OutOfMemoryException. This is about a 7x bump in memory.

Git bisect pinpointed the regression to commit 62ac1047a18979bea1f5d6c668eefeaaae39d64b

Skimming that commit, nothing immediately jumps out at me as a significant change to what we already did, so I'm not sure exactly what caused this regression.
