Fix segfault in macOS with 1989/paul

The problem was that the int * needed to be a long *. It became apparent
to me when evaluating it with lldb as I noticed a pointer was long, not
an int. This does not cause a problem with linux. I have no 32-bit
system to test but I don't believe this will be an actual problem.
