Yes, but to make a long story short, I was stymied by the rocket science of class clusters and abstract classes. The error says that +initWithObjects:count: was sent to NSCFArray. So first I reverse-engineered from savannah.gnu.org what are the argument types. They are id* (a C array of ids), and an unsigned int. Then I constructed an invocation using the NSClassFromString(), @selector(), etc. But upon invoking, the system told me that +initWithObjects:count: is not implemented the *abstract* class NSCFArray. I don't know what the concrete subclass is :( Another thing I tried was to replace the method +[NSCFArray initWithObjects:count:] using Method Replacement. But it was never invoked, probably for the same reason, although interestingly -[NSCFArray objectAtIndex:] is invoked with great frequency. So rather than fight all this stuff I thought I'd ask the more general question: Is it possible for the same exception in the same build to crash the app on one system but be handled with no crash on another system. I believe it has something to do with exception handlers but I've never learnt this very well. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
