Archlinux xorg.log

Running under Archlinux wine (1.1.7-1) it also crashes much the same, but got at least a little more output about the error that I'm attaching.

When I did the same in Fedora Core neverwinter didnt crash and return to desktop, but that's only because the rest of the system crashed harder and froze.

Could-be a problematic shader?

I don't know if this can be important, but replacing the glLoadProgramNV with a stub make Nwn run stable (for those intrested in the stub visit the Linux forum at Bioware's site)

I also made a wrapper glLoadProgram library, to inspect what the calling parameters were. I found out that it's called as:  glLoadProgramNV(34336,1,2880,str)                                                                                                  

Translating the first to hexadecimal, and grepping Mesa/includes gives:
glext.h:#define GL_VERTEX_PROGRAM_ARB             0x8620
glext.h:#define GL_VERTEX_PROGRAM_NV              0x8620

I did not find much documentation about given call, (where can I find it?) from google the following should be ID, length of program (stripping out comments), and some kind of pointer to the program. In this case the pointer is a shader program string, so it's: glLoadProgramNV(GL_VERTEX_PROGRAM_NV,int id, int prg_len, char *prg)

I remember that Eric checked the shader program strings in the main executable (bug 13728). However, this shader program is not listed with `strings nwmain`.

I'm attaching it for easy reference, adding some newlines for readability.

I get this problem on an ATI R500 (x1950 pro)

i686 Phenom with 32 bit userspace
Debian  2.6.26-1-686
libgl1-mesa-dri                  7.2-1
xserver-xorg-video-radeon        1:6.9.0+git20081129.783cdb73-1
libdrm2                          2.4.1+git+20081116+930c0e7-1

Neverwinter nights HOTU v.1.69 (final)

The game crashes with "Aborted"

If I use Joels LD_PRELOAD stub to remove calls to glLoadProgramNV(...) then it works fine (though obviously some textures are missing).

I also get this problem on another machine with an ATI Technologies Inc RV350 AR [Radeon 9600]

Athlon 3000+
Debian  2.6.27.4
libgl1-mesa-dri                  7.2-1
xserver-xorg-video-radeon        1:6.9.0+git20081129.783cdb73-1
libdrm2                          2.3.1-1
Neverwinter nights HOTU v.1.69 (final)

The game crashes with "Aborted" as soon as I select a robe/cloak for a character.

If I use Joels LD_PRELOAD stub to remove calls to glLoadProgramNV(...) then it
works fine (though again, obviously some textures are missing).

google for LoadProgramNV, not the gl.... variant

The error I get is nwmain: main/state.c:1030: update_program: Assertion `ctx->VertexProgram._Current->Base.Parameters' failed.

I've tried replacing the VP with various other programs but all give the same result. (I don't know what a minimal VP should look like though)

I used:
!!VP1.0 # Minimal vertex program.
DP4   o[HPOS].x, c[0], v[OPOS]; DP4   o[HPOS].y, c[1], v[OPOS]; DP4   o[HPOS].z, c[2], v[OPOS]; DP4   o[HPOS].w, c[3], v[OPOS]; END

    mesa: remove invalid assertions that programs have parameters
    
    Fixes failure with demos/fplight.c

I can confirm that commit a4a5a37f2760eca97b85f699c932c746da4d8e6c stops this crash on NWN :)
I got the source for debian mesa 7.2 and simply applied the (now massively offset) patch.
NWN then runs and displays some of the previously missing textures - including cloaks; I have noticed one texture doesn't display properly but that's a different bug.

Now aborting on brw_upload_vs_prog at /mesa/drivers/dri/i965/brw_vs.c:93
