Looks like still more unit-at-a-time problems with Objective-C, this 
time only on Darwin :( .

With the following code (which is valid and should not seg fault) seg 
faults when runs on Darwin with -funit-at-a-time only as an option:
---------------------------------------------------------
#include <objc/objc.h>
#include <objc/Object.h>
@interface A : Object
@end
@interface B : A
@end
@implementation A
@end
@implementation B
@end
int main()
{
        B *b = [B new];
        return 0;
}
-----------------cut------------------------------------
It does not seg fault on linux, remember that on Darwin there are 
Objective-C sections in the asm.
