Avoid undefined arithmetic on nullptr in buffer_offset function 

Not quite sure why it was done that way. Maybe to ensure we work with byte-pointers of correct size or something?
Anyway, this doesn't seem to be defined in c++, so let's try working with a cast instead.
Just something cppcheck tool complained about.
