ChatPacket cause game core crash.

[piktorvik 20]

Dear everyone!

I'm trying to solve this issue, but i didn't find anything. I'm ask for your help guys maybe someone can suggest something.

Serverfile: martysama 5.4 (boughted).

In the source i have vegas multilanguage + pickup (boughted).

LLDB:

input_login.cpp 85 line (sometimes it's item_drop_bonus etc..):

    exp_bonus = CPrivManager::instance().GetPriv(ch, PRIV_EXP_PCT);

it's chatpacket:

ch->ChatPacket(CHAT_TYPE_NOTICE,
            LC_TEXT("°ćÇčġ %d%% Ăß°ˇ Čąµć ŔĚşĄĆ® ÁßŔÔ´Ď´Ů."), exp_bonus);

(When entering the game i see this chat message and it's working fine.)

 

GDB:

 

Syslog:

What do you think? The server is crashing very often when someone entering the game. 

I've checked the locale_strings line by line, translates, source chatpackets, but i didn't find the issue.

Marty and VegaS tried to help me, but it was not enough.

 

I don't expect anyone to help me for free. I can pay for your help & time.

Thank you in advance!

Hi, as far as i see, the problem at ChatPacket format argument, it comes from LC_TEXT, the memory address what comes from Vegas's LC_TEXT modificated function is empty, freed region or something is not correct inside that function, and the vsnprintf cant acces to that correctly. I dont know that multilanguage system, but it is a possible point to the problem location.

I dont know the full history of this problem, but it is my tip in first look.

Have a good luck.

Hi, unfortunately not. That project was frozen there and then. Are you struggling with the same thing?

Hello.

Thank you for your answer!

Yes, same thing. Marty source, Vegas multilang and crash core at ChatPacket.

I haven't checked the issue in depth, I wanted to ask here first since I've seen you encountered the same issue thinking that it will save me some time.

 

Issue not happening on same ChatPacket call, it happens at random it seems.

UPDATE:

I think I fixed it. I used to replicate it easily now I can't anymore. I think it had to do with the locale_string format or maybe some unsupported characters of the other languages. I replaced them with my english locale that was good and works fine now.

I can't explain but it worked so far.
