Using git I get exactly the same output than Daiki Ueno: the boundary
problem has gone, and another problem has appeared.

So I guess that if you close this bug, then another needs to be opened
for the new problem.

And, if you have enough time, please provide patches to 23.x (sorry for
insisting).

Many thanks,
