The variable pending-undo-list is used by for example undo-start and
undo-more. The doc strings says that you should first call undo-start
and then you can call one or several times undo-more later.
If those calls are done in different buffers it looks like trouble to
me. Should not pending-undo-list be buffer local?
I think for the reason above that it should be buffer local and I also
think that it should be permanent buffer local then.
I asked before if it should not be permanent buffer local. That was said
not to be necessary since it is not buffer local. I think that is wrong,
but please see the thread here:
