I can't resist trying a Hail Mary answer. If I'm right can I have a million dollars, please? One possibility to consider is messaging a nil object. That's normally safe (you get a reliable return value of 0/nil/NULL). But if the method return value is a *structure*, the return value is unpredictable. (And, yes, I learned this the hard way. Even though I already knew it.) One thing that I *think* is different about PPC is the set of rules for how structures are returned (depending on how big they are, and whatever other factors). So, sending a structure-returning message to a nil object may fail differently on PPC, but differently in a repeatable way, perhaps. Or not. Message me off-list about where to send the million dollars, ok? _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
