Possible buffer overrun if the number of "card" and "device" are absurdly high, especially on 64-bit platforms.

The size of "int" is 32 bits even on 64-bit platforms.

Seems you're right, then I learned something new today :-)

Although this might be compiler dependent, and some exotic platform might decide otherwise in the future?

As far as I can see, there is no bug.

Even for 32-bit platforms, you would still overrun the buffer if you set card = device = −2147483647.
