Application error on i386, works on x86_64

Question

I tried switching architectures to my Xcode project today because I was going to use low-level QuickTime materials that have not yet been ported to 64-bit. When I compiled earlier on x86_64, my application worked fine. Then I switched the arch to i386 and the arrow, my application continues to crash on startup.

The strange thing is that the stack tracker has nothing to do with my own code.

Any ideas?

I assume that you created objects in nib that are unsafe in 32-bit mode. For example, you can make assumptions about the size of an object that is not true, for example, using double instead of CGFloat or int64_t instead of NSInteger.
