this problem is from... 2013!

Is there anything we still need to fix in this area? If so, can you
send it as a patch against current maint branch?
Yes, there's definitely still a problem similar to the one reported - although I have yet to pare it down to a reproducible case.
I need to look at this more to understand why the fix that was done doesn't seem to work. Once I understand that, I'll be close to creating a patch. The issue is that I don't know this code very well, so any fix I make might be wrong for some other reason I don't understand.
Thanks,
