Segmentation fault

[schdorm]

I just built a AMD64-Client ... as there is no official 64bit client [Linux, Ubuntu].

Everything worked (and works) fine ... except playing: there is no problem with viewing a game - to "drive around" in spectator mode but if I want to join a team there occurs a "segmentation fault". I hope anyone can help. I'll try to get some more information about the crash.

Edit:
Well, gdb can tell me the following:

[...]Starting program: ~/zb_s/games/tank/tank
[Thread debugging using libthread_db enabled]
User data directory is "~/.config/QuantiCode/Zero Ballistics/"

The same happens when hosting an own server, but in this case immediately after the server is ready:

Btw.: the x86-version runs without problems - except some problems with the temperature of my cpu.

I found the line, where the segfault occurs: line 235 AND line 236, TerrainData.cpp

Code: Select all

231    for (int i=0; i<4; ++i)
232    {
233    for (int j=0; j<4; ++j)
234    {
235    x_interpol [i] += h_base[j-1 + (i-1)*width_]*cx[j];
236    xd_interpol[i] += h_base[j-1 + (i-1)*width_]*cxd[j];
237    }
238    }

(only if both the lines are commented out, the segfault doesn't occur ... btw: it looks really funny driving around the tank without these two lines )

As I'm not familiar with all that code, I can't do anything else right now.

This seems to be the same issue as in this topic: viewtopic.php?f=4&t=1011 It can actually be fixed.
