Do you have ANSI-C compiler ?
Is your system running in 64-bit mode ?
This smells like non-ansi treatment of 64-bit wide
pointers where default type size is 32 bits.
(Alphas have this same problem if compilation is not
done in ANSI-C mode.)
If that turns out to be the case, I propably need to
have some hands-on experience with your host to tune
the autoconfig to understand AIX 126.96.36.199 better.

Try setting breakpoint at sp_install(), and see what parameters
it gets when it is called. (step a few "next"s, and print the
parameters - especially the q, and then "continue")
