Rony,
I just thought of one more thing that could cause the error you're
seeing. If you do an AttachThread() at some point and neglect to do a
corresponding DetachThread() before returning to your caller, you'll
end up with a corrupted activaation stack that will result in problems
with legacy callback APIs like RexxVariablePool or RexxStemSort.
What;s showing up in this traceback very much appears to match what
might happen in that sort of situation.
