Any guides how to fix crashes?

[ilija]

Hey , i always update my core to the newest , and sometimes there are new crashes comming.

I know the basic stuff of C++ , almost all basic you need and i wonder how to fix them , are there any guides. I already have GDB and see the output crashlogs.

It is just last time there are more and more crashes comming , appears every 2 hours , very annoying!

Thx

Sure, it's easy.

1. Read backtrace to find the point of crash.

2. Browse through source code to point of crash and find the problem.

3. Fix the problem.

4 Done.

Seems to be easy how you say , only , sometimes i get so big log that i dont know what line i should look at, but normal is it first line where it says <value optimized> right?

Patman , i get crashlog , it is like 200 lines , where should i start? Something like this :

It is to much information, how should i set up proper the config , im running debian 64bit , also got other issue , how to compile 64bit , because if i do ingame .server info , i get 32bit linux, im using 64 bit.

Thanks you very much , Greetz Rusfighter
