etc.
I found this one by pasting in a function that didn't work. And reduced it
actually executing the function.

Message:
This is the general stack and does not give any clue on what object it is
attempting to access.
Also it seems a glitch depending on an unspecified sequence of actions.
The erroneous function might give an indication if the parser/type
resolver,etc.... left something
unmarked.
The bug is archived.
