Indeed, but I'm talking about the opposite situation. Something in Cocoa throws an exception up through *your* code not you throwing an exception through *Cocoa's* code. Code using C++ RAII idioms will function properly in the presence of Obj-C exceptions on the 64-bit/iPhone runtime. The same cannot be said of code on the 32-bit Mac runtime. -- Clark S.
