void main()  safe
{
    long[2] a;
    auto b = cast(ubyte[])a; // error
    auto c = cast(ubyte[])cast(long[])a; // works
}

main.d(4): Error: cast from long[2u] to ubyte[] not allowed in safe code

Without  safe mode there's no error.

Slicing a static array is equivalent to taking the address of a local variable,
which is illegal in safed.  The second case works due to bug 8838.
