Item 85 from the old PROBLEMS file (no test case available):
----------------------------------------
pea can force a value to be reloaded into an areg which
can make it worse than separate adding and pushing. This can only
happen for adding something within addql range and it only loses if
the qty becomes dead at that point so it can be added to with no
copying.

Also fine, not closed. Great to see that you pay enough attention to stop the
reporter from closing his own PRs. I wish you would be just as fast with
actually doing something about them. It is not even clear whether these
problems still exist!
If this still not OK with you, I suggest you do something about these 15+ years
old problems, or close these and re-file under your own account. They may not
bother you but I don't want them anymore in my list.

No response from m68k maintainers for more than 5 years. That may be a record.
This just clutters my bug searches. WONTFIX seems the most logical "way out".
