The problem is that changing from the current behaviour (undefined in C, but typically a shift by (PHP_INT_MAX - $bits)) to do what you’d expect (shift in the opposite direction) would be a silent BC break. I think it’s better to just stop it altogether and raise an E_WARNING, where it’s at least obvious something went wrong, than change this behaviour silently. > In the patch you use SIZEOF_LONG.
