inet_ntoa / inet_aton is known to be broken on irix 6.x - the fix is
generally to get a known good version of these two functions and
recompile.

Try http://freeware.sgi.com/shared/howto.html which says there are
workarounds for these routines, in libgcc.a

a.. gcc vs. cc
Code that runs fine when compiled with SGI cc and doesn't run when
compiled with gcc might be calling functions compiled with MIPSpro C
that get passed or return structs that are smaller than 16 bytes but not
8 bytes long. gcc and SGI cc are incompatible in the way they pass these
structs so compiling with gcc and linking with a shared library that was
compiled with the SGI cc) can cause these problems. There are very few
such library functions, but inet_ntoa, inet_lnaof, inet_netof,
inet_makeaddr and semctl are all examples. Work-arounds for these
particular routines have been built into libgcc.a, but that is not a
general fix. If you find more instances in IRIX libraries please report
them. Often a small wrapper procedure that realigns the problematic
arguments will avoid the problem.
