Well, how about this:
void foo(pointer(int) x) { *--x = 7; }
void bar() { array(int) q = ({ 47, 11 }); foo(&q[1]); }
I think this is slightly disturbing. bar has not shared a reference to q[0] with anybody, and yet the value of q[0] gets changed under its feet.

Well, the most severe hazards with C pointers wouldn't exist anyway, such as indexing out of bounds and casting between pointer types. What other issues can there be?
