  I am unable to understand that you are _not_ saying that the cause of the
  failure was that there should have been an exception handler (that did
  nothing) for this situation, but wasn't, and this flies in the face of
  the gist of the report, which was, and I repeat myself: that the bug was
  to let code run that should not have run to begin with.

  ObCL: IGNORE-ERRORS is an exception handler.
