I'm not so sure about this.

I have two systems with very different behavior, one is an AMD x86_64 box running openSuSE 10.2 and the other is a Sun Ultra1 Creator running OpenBSD 4.0.  I have compiled centericq several times on the AMD, including 4.21.0 and 4.21.0 + automake & msn patches and have had no problems whatsoever with MSN or any other protocol.  On the Sun Ultra1, I have also built both plain 4.21.0 and 4.21.0 + automake + msn patches.  No centericq built on the Ultra1 even start if msn is enabled at compile time.  

That said, I've also downloaded and built the libMSN 3.2 library from the website and built it on the Ultra1.  If I run the supplied "msntest" program, it works flawlessly, which implies to me that the libMSN works just fine and that the problem is somewhere in the centericq code.

I saw a post somwhere recently (but I can't find it again) that speculated the issue has to do with the compiler used.  openSuSE 10.2 has gcc 3.5 and OpenBSD 4.0 has gcc 3.5.  There's no gcc 4.x available for OpenBSD, but I'll try to find a 3.5 for SuSE and see what happens.

I'd like to help find the problem, but I'm not much of a coder and have zilch for C++ experience.  That's not going to stop me from digging through the code, I'm just not expecting any results.
