Robby, __int8 limited to: -128 to 127.

Are you ( Robby ) asking about the contents of A1, the __int8 ?
or A1 the pointer ? What does “ sizeof( int * ) ” return ?

If it's the __int8 ( i.e. “ sizeof( int ) == 1 ” )
then it can't be 256, as it's limited to: -128 to 127.

If it's the pointer you're talking about,
then you have to tell us what it's value was before entering the loop.
