Dear Sirs and Ma'ams,

Whenever a certain user QUITs while running the andchat (http://www.andchat.net/) client for android znc seg faults thusly.

ZNC compiled from git source.
debian squeeze

Do you need any more information?

Thank you

Which modules do you have loaded? Have they been built with znc-build from the exact same znc version you are running?

Global modules are:

LoadModule = webadmin
LoadModule = imapauth imap.gmail.com +993 %@lindenlab.com

for that user:

LoadModule = chansaver
LoadModule = controlpanel
LoadModule = webadmin

i did a git clone

./autogen.sh
./configure --disable-optimization --enable-debug
make
sudo make install

are RPL_CHANNELMODEIS and RPL_CREATIONTIME, respectively. Maybe it has nothing to do with QUIT, because those look like automatic replies sent after joining a channel. Looks a bit weird that they have a different target, but this has probably nothing to do with the crash.

The ZNC version you are running has some recently introduced new module hooks (https://github.com/znc/znc/commit/76bfa99dd02f0fed0d8c8e4b678766c95a167205), so I was suspecting the crash would be due to binary incompatibility. Those look like built-in modules, though, so they should've been rebuilt correctly together with ZNC. Do you remember if you did a clean or incremental build?

Could you run znc with the --debug argument and make it crash quickly? Perhaps that helps in figuring out what went wrong.

I wanted to make sure i had a clean setup, so i tried to compule again from a new git clone. it complained about my compiler version, so i downloaded the 1.4 tarball. I've compiled but the master crasher has left for the day. I'll get back to you as soon as I can.

Thanks

Jerm

same thing.

I can connect with textual, and it works fine. I can send messages, quit, whatever. landon connects with andchat, crashes it.

How come the debug output doesn't match with what ZNC 1.4 source code does?

2014-08-21 17:56:31.440318 IRC -> ZNC [:irc-phx1.lindenlab.com 324 landon_ #lindenlab +]

vs. https://github.com/znc/znc/blob/znc-1.4/src/IRCSock.cpp#L135

DEBUG("(" << m_pNetwork->GetUser()->GetUserName() << "/" << m_pNetwork->GetName() << ") IRC -> ZNC [" << sLine << "]");

The (username/network) part is missing. Is the output or ZNC modified, or what's going on?

Interestingly, the missing part does essentially the same thing where it crashes in stack frame 4: CClient::GetFullName (src/Client.cpp:751): https://github.com/znc/znc/blob/znc-1.4/src/Client.cpp#L751

Uhm, check znc --version AND /msg *status version. What are the odds of starting a wrong/older version of znc instead of the intended one?

It also breaks in a similar way running on different machine that is debian jessie with the packaged version of znc (1.4-1+b1)

Reproducing the crash is not as simple as connecting ZNC with AndChat. I had no problems with AndChat v1.4.3.2.

The best I can think of is to paste all relevant debug output all the way from where the problematic client connects and to the segfault. Then we can see the whole sequence of events, and details of the IRCd etc. which might help to setup an environment that can reproduce the problem.

PS. To avoid confusion, please avoid manipulating the debug output otherwise than filtering out irrelevant lines and passwords.
