Really fix segfault in 2001/bellard.otccex.c

The segfault fix (that prevented it from working at all) that I made a
while back was not actually complete. It should work fine now (famous
last words but it does appear to work now with different values where it
crashed). Some ints were used as pointers (including a function
pointer).

It should be noted again that 2000/bellard itself does not work but
having this program bug fixed will be helpful for anyone who might want
a crack at fixing bellard.c (see bugs.md).
