Small test-case:

extern(C) void fail(int[4] x);
extern(C) int[4] fail2();

extern(C) void c_ok1(ref int[4] x);
extern(C) void c_ok2(out int[4] x);
extern(C) void c_ok3(int[4]* x);
extern(C) ref int[4] c_ok4();
extern(C) int[4]* c_ok5();

Have I covered everything?

The implementation of D associative arrays is opaque, so why is this allowed?

extern(C) void foo(int[int] aa);
void main() {}

Well this is less dangerous than the OP case, but maybe it should be disallowed. Another bug should be opened for this.
