Thx for your efforts on this, much appreciated. It seems more than just
one or two users are hitting this crash and a fix despite all your
tremendous efforts it not yet in sight. Hence please allow me to ask:
would it cause a significant regression for users of 6.5 and later, if
we'd temporarily revert the culprit and anything depending on it until
this is solved? Because if not I wonder if we should go down that route,
even if it's a drastic measure; but then Greg could fix this in soon in
6.6.y as well.

Ciao, Thorsten
