Since only you can reproduce something pathological, could you please
create the bug report?  Makes no sense if I do it and get questions
about the recipe that only you can answer.

If there are markers, undo probably needs to handle them.  Is the effect
really that drastic?  Aren't markers only put into buffer-undo-list when
undoing, but not for all other editing operations?

Anyway, an important question is why you see 18 different markers in
your buffer.

Thanks,

Michael.
