You should take this over to the Xcode mailing list. I'm not clear
why gdb
seems to "stall" in certain situations involving watchpoints.
It is just very, very slow. I've clocked it at over an hour to run
one call to CreateNewWindow (in Carbon).
This is just a performance issue in the current debugger. I don't
know if they plan to address it, but the upshot is that watchpoints
are basically useless on current hardware until they improve the
speed. :( I have an open radar on the performance issue (as well as
Xcode's general uselessness with creating watchpoints) and have heard
back that it's known and they're working on it; don't know any more
than this.
It is possible that the OP's problem is due to the object being
released (not enough retains?) or memory smashed somehow; too bad
it's hard to tell when watchpoints are busted! :(
