It might work on a DLL compiled with -O0 -g, but here we > have a problem that the function gets inlined everywhere it's called. So > instead I set an unconditional breakpoint there and let it run until I hit it: 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. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
