Test case.

DMD2 cannot cast away the immutable modifier a variable, or raise a suitable
error for it.

Attached code outputs:
0

Where the following is expected:
0
2
0
2

... or some kind of error.

Casting is the tool which allows you to break D's typesystem. This behavior is
completely expected and is by design. If you use a cast, it's expected that you
know what you're doing.

Note that your code will not compile with  safe:

test.d(5): Error: cast from const(int*) to int* not allowed in safe code
