Eggdrops later than 1.6.1 dies on /dcc chat

Somewhere, probably in the resolve code, is something that makes eggdrops later than 1.6.1 die horribly on /dcc chat eggie.

I'm using a Windows DNS server on a remote machine, I bet that's it, but eggie shouldn't die from it. The actual message from various versions point to a line in server.c but it makes no sense, probably due to macro expansion. For what it's worth, here's the error:

[00:32] Timeout/EOF ident connection
[00:32] * Last context: server:server.c/1395 []
[00:32] * Please REPORT this BUG!
[00:32] * Check doc/BUG-REPORT on how to do so.
[00:32] * Wrote DEBUG
[00:32] * SEGMENT VIOLATION -- CRASHING!

And just to be cool it also dies on +host DCC commands (I could dcc to it through a reverse DCC command within a script):

[01:09] #Micke# +host Konstiga_ *!konstiga_e@*.hs.bonet.se
[01:09] * Last context: tclhash.c/677 [Tcl proc: *dcc:+host, param: $_dcc1 $_dcc2 $_dcc3]
[01:09] * Please REPORT this BUG!
[01:09] * Check doc/BUG-REPORT on how to do so.
[01:09] * Wrote DEBUG
[01:09] * SEGMENT VIOLATION -- CRASHING!

Did I do the mistake of thinking older linux work work, that windows DNS servers would work or is there something else I could change? I have NO intention of going through 4 hours of registering pain JUST to let someone know about this bug, so this is it. Maybe the eggdrop peaked at 1.6.1 (I've tried 1.6.7, 1.6.10 - both dies on these things while 1.6.1 works perfectly).

Btw, linux version is 2.2.16-22, gotten from redhat something a while back.

Try to reproduce this when you compile your bot (use the latest version) with make debug. If you can, run a gdb on the core file (gdb eggdrop -c core, then type bt at the prompt), fill out a bugreport, and send it to bugs@eggheads.org.

If you can't reproduce with make debug, I suppose sending in a bugreport might be helpful anyway.

Yes, well, of course I can reproduce it. It -never- fails to happen - /dcc chat <botnick> is a 100% certain instant crash.

However, what with all the registering and crap I had to do to register a bug, this is it. Apparently it works for everyone else, so I'll just assume eggdrop is no longer for me (used it since pre-1 versions but since 1.6.1 works I may as well stay there).

I did report the simple_sprintf used with %lu once a ways back and that never disappeared (took like 10 versions) so I'm not all that confident in bug reports anyway =) Too bad noone else has this problem or it would probably have been fixed already.
