*sigh* probably memory corruption could you run it under valgrind and see if there's any useful info?

https://github.com/FreeRADIUS/freeradius-server/blob/master/doc/bugs (see section 5).

I'd do it but valgrind is completely broken under OSX currently.

Also when you build your RPMs could you make sure to pass --enable-developer to turn off optimization so we don't get all those <value optimized out> messages.
