From my experience last night you should be able to use something like:-
b 113 if ( 0 == (**(verifyable_object **)objectptr)

If not here at least it hits that break ~ 280 times before blowing up so
setting a conditional on that occurrence should help.

Unfortunately I'm currently testing a none threaded compile on the machine
so cant check myself just now.
