Segfault running pmd with GenCopy plan #553
Description
This crash happens even with larger metaspace size. Tested with slowdebug and release - both have segfault crash. It's been consistent for me.
This does not segfault on stable dacapo. It happens with both dacapo-evaluation-git-29a657f and dacapo-evaluation-git-f480064 though.
Running pmd with standard openjdk without passing it any flags does not have the issue.
