I'm not sure if I should open a new bug or not, but since this one is still
open, I'll put it here.

The array cases seem to be fixed in DMD 2.14, but the very same problem still
exists with pointer types, for example:

void testcases()
{
        int** intPtrPtr;
        int*** intPtrPtrPtr;

        const(int)** h1 = intPtrPtr; // Error here
        const(int*)* h2 = intPtrPtr;

        const(int)*** i1 = intPtrPtrPtr; // Error here
        const(int*)** i2 = intPtrPtrPtr; // Error here
        const(int**)* i3 = intPtrPtrPtr;

}

Similar issues also exist for associative arrays.
