I just sent a new reply on the bugzilla thread just as you responded.
There is certainly a bug there for which I just posted a new patch to be
tried. I am just not sure that this will fix the entire crash that is
seen by the reporter (I am still unable to reproduce it).

I will try my best to get to the bottom of it, if not I'll submit a
patch so that we start with TSO disabled.
