ORA-00600 during execution

[MickeVr]

During test execution with utplsql-cli, I get the following error. I am not sure if it is really an issue in utplsql or of the database

ORA-00600: internal error code, arguments: [kollgdur1], [], [], [], [], [], [], [], [], [], [], []

Hi @MickeVr
Thanks for putting this into an issue.
At this time I'm unable to help. If you are unable to reproduce it, most likely we are unable to reproduce it even more.

If you manage to fins steps to reproduce, please share those. I assume that the issue is on Oracle side (as in most cases with ORA-00600).

Please keep us posted if you hear back from Oracle on that issue or if the issue is happening regularly and it is becoming a blocker.
