puts("Foo!");

main()
{
Method method = class_getClassMethod([Object class], @selector(alloc));

/* INCOMPATIBLE to Apple! class_pointer should be isa!! */
class_replaceMethod([Object class]->class_pointer, @selector(alloc),
(IMP)alloc, method_getTypeEncoding(method));
[Object alloc];
return 0;
}
> If you change Object to NSObject and class_pointer to isa, it works on OS X.
