The patch proposed by David is really non trivial wrt. potential side
effects. I have provided my review feedback [1] and it didn't get
any reaction. I really believe that we need to debug this properly. A
reproducer would be useful for others to work on that.
There is a more fundamental problem here and we need to address it
rather than to duck tape it and whack a mole afterwards.
