OK thanks for the info. The offending commit just enables using quite a
few of the newly added code before that. So the problem could be in any
of the newly added code.
Unfortunately I can only look at this during my limited time in the
evening and I have to setup my system to compile and run this, so I
won't be able to get to the bottom of this as fast as I'd like to.
