Maps crashing wsw 0.6 and 0.7

As I promised I did a debug build (wsw 0.7) to get the dump.

Program received signal SIGSEGV, Segmentation fault.
0x080c8746 in R_LightForOrigin (origin=0x84da0a4, dir=0xbffff2c8, 
    ambient=0xbffff2dc, diffuse=0xbffff2ec, radius=36.5507812)
    at ref_gl/r_light.c:306
306                     lightarray[i*2+1] = *r_worldbrushmodel->lightarray[bound( 0, elem+1, r_worldbrushmodel->numlightarrayelems-1)];

Most of my maps crash with that. The problem is that I cant backtrace because my computer freezes during the crash, I have to exit X and kill gdb.

Is that because warsow freezes or because gdb freezes? You can kill Warsow just fine which leaves you at the gdb console.

BTW lol at the italian bug :D

Oh I forgot that when I kill wsw then the screen (X) remains black and keys don't work anyway.
Only alt+backspace (logout) and ctrl+alt+f1 console work


I'll have to find a way to dump backtrace automatically, log only leaves me the output not backtrace. I saw some scripts for gdb but dont wanna use some random shit form the web.

I tried to blindly type but keyboard is blocked.

Btw is there way to run gdb from console but execute wsw on a x display. That way I could access gdb during freeze

post a sample map so I can reproduce the bug locally

Ok this one crashes every time. Same error as others (the video there is not related to bug btw)
just go near the ceiling as a player

Dl'ing map nao, i haven't been able to reproduce on your other maps yet.
And for the record, you can run X apps from a vt, just do 'export DISPLAY=:urdisplay' first

EDIT

Ok tried map, can't reproduce bug in wsw0.7 didn't try 0.6 :(. I'm on 3.4.4-3 arch x86_64 (same as you?) with wsw0.7b2 built from source.
(updated 2012-07-17 10:46:22)

Tried export DISPLAY=:0.0, after switching to X whole computer froze hopelessly.

Vic are you running 64 bit as well ?

Because I'm on 32 bit and crash every time I go near the ceiling AND I'm not the only one. Many other crash too (on wsw 0.6 when the map was on a test server).

The bug is on windows and linux.

Vic runs Windows 7. Doubt you'll get any care for any Linux stuff, especially as it's not Ubuntu.

I mean that maybe only 32 bit is affected :D

I dl wsw 0.7 to windows and test it there :P

I'm running ubuntu

It'd be rly weird to be a 32bits only issue, but if it is I don't even have a 32bit install around :S. I also only run wsw in windowed mode and am too lazy to try in fullscreen b/c I'd have to disable dualhead first.

yes yes yes. I was able to run in windowed mode then ninja alt+tab to terminal and backtrace ^_^

I really hope it works and its just my bug. It crashes on my computer like crazy. I lure some people into my server and see what happens.

Me -> Hey wanna see my cool server.
Victim -> Sure!
connecting ...
Victim -> Arrrghhhh!!
.. dies IRL

Care to do this one more time and print some of those local variables? Like
'print elem', 'print *r_worldbrushmodel' once the program breaks. This might give a clue on
whats happening, but since Vic can't reproduce that its hard to look up to. Wild hunch is that you might have a too large map or too much lights or something.

UltraK1ll, please open up r_q3bsp.c, find the function Mod_LoadLightArray_RBSP, then change the line that says:

*out = loadbmodel->lightgrid + LittleShort( *in );

to

*out = loadbmodel->lightgrid + (unsigned)LittleShort( *in );

See if that fixes the crash and then report back here, please :)

hm, in the same function, please try changing:

short *in;

to

unsigned short *in;

OH YES YOU ARE MY HERO VIC

wtf making a var 2x bigger fixed the stuf lol

EDIT: so if all variables in wsw that would not need to be negative were unsigned then we would have less limitations :D

Weird is that there are bigger maps with more lights out there and my map crahsed

EDIT2: I'm doing make clean then make and double check ^_^

EDIT: Ran the map 6 times with fullscreen and windowed mode NO CRASH YAY!!!!!111 one one eleven.

Also tested slide_arena_remix, works!

PS
Correct me if I'm wrong but if you compile wsw on 64 bit computer then the variables are bigger?
