The following code is rejected even though it should not be:
#import <objc/Object.h>
union a { id g; };
void f(union a);
void g(Object *b)
{
f((union a)b);
}
-----
Object* should be able to goto id without any troubles.

The code is invalid, the related C testcase:
union a { void *g; };
void f(union a);
void g(int *b)
{
f((union a)b);
}
Which is rejected everywhere.
