Test case:

--------------------------------
static assert({
    int x = 123;
    int* p = &x;
    float* q = cast(float*)p;  // <-- unsafe pointer cast
    return *q;
}());
--------------------------------
y.d(2): Error: CTFE internal error: illegal pointer value cast(float*)123u

Assertion failed: (isStackValueValid(newval)), function createStackValue, file
interpret.c, line 4998.
Abort trap: 6
--------------------------------
