Coredump on AIX 5.3

Hello, I am trying to install freeradius 1.1.6 on AIX 5.3 with gcc 4.1.1. If I follow the basic instructions it seems to compile and install. However, trying to run "radiusd" with any options results in a coredump. Has anyone managed to install a recent freeradius release on AIX 5.3? What configure options did you use? Any special modifications to the source required? Thanks. ---Hillel
