 Switching to gcc-3.4 resolved the crash issue. I do notice one other problem. Hostname lookups are failing instantly, there's no delay where it tries to do a lookup. The DNS server is available and working correctly, as witnessed by doing nslookup on the command line.

[Edit]: hostname lookup problems were caused by a GCC 4 compiled c-ares library apparently being linked to during IRCd compilation. Removed it, hostname lookups work fine now.

 Ok ;p.

Hmmm... gcc4, is that in 'unstable'? Can't get it in 'testing'...

{Presumably due to ABI changes (C++ only) they are a bit hesistant...? ;p}
{edit: seems gcc4 hardly has any speed improvements anyway}

Hehe.

Yup, it's what is classified as "testing/unstable" in Debian. I'm a Debian noob, so I don't claim to know how they name their releases, although I understand "testing" in Debian would be pretty much classified as "stable" anywhere else.

gcc-4.0 is in testing

I have no problems with it and i even tried now the just released gcc 4.1 on my debian sarge server and unreal seems to work fine with it

Ah ok, seems I switched my box from testing back to stable a few months ago, nevermind my not-in-testing comment ;). I usually run testing indeed (well, on this development server).
I'll see if I can try here as well.

penna: ok :p.

so hm, can this be closed, or not?

Was it simply caused by forgetting to run ./Config -quick after upgrading your compiler? (and hence the libraries such as TRE and c-ares were not recompiled)

Or.. ? :)

You're right. You can close.
