[IRCServices] Segfault on Opteron (64-bit) Linux

[Liverbugg]

I'm trying to run ircservices on a dual opteron server and I'm getting 
segfaults.  I've tried 5.0.31, 5.0.38, and 5.0.41 over the last few 
months and just had enough time recently to try to debug.  The computer 
is a dual Opteron 242 running Gentoo Linux.  The server I'm trying to 
link to is Unrealircd-3.2 running on the same machine.  Ircservices runs 
fine with the same config linking to the same server if I run it on a 
32bit x86 machine.

The compile has lots of warnings that I don't see on a 32bit machine like:

modules/statserv/main.c:127: warning: cast from pointer to integer of 
different size
modules/statserv/main.c:127: warning: cast to pointer from integer of 
different size

This is what I see in the the log when running ircservices -debug:

[Oct 04 20:36:13.560828 2004] IRC Services 5.0.41 starting up (options: 
debug)

:*** Looking up your hostname...
[Oct 04 20:36:32.983294 2004]

If I run it with ircservices -debug -nofork all I see in the log is this 
(this is from 2 tries):

[Oct 04 19:59:43 2004] [Oct 04 20:04:50 2004]

If I run it with no parameters the server sees services come on line but 
die right away:

-squall.local- *** Notice -- (link) Link squall.local -> 
services.lanchelms[@127.0.0.1.6677] established
-squall.local- Lost connection to 
services.lanchelms[127.0.0.1]:Connection reset by peer

but if I run it with -nofork the server never sees the connection

There is no core generated, even when I compiled with ./configure 
-dumpcore -cflags -g -defaults, but here is what gdb shows when running 
ircservices in it with -nofork -debug:

Let me know if theres any other info you need or if you want access to 
the machine to debug.

Thanks,
