Sorry about the other mail. I made a small mistake :/

That's interesting. I first get an error while initialising OpenAL :

General: soundcard = <nothing>
Sound: SOUND ==> Initializing OpenAL...

But if I run it without sound or if I ask it to continue, it just crashes like
that :

on GL_SGIS_generate_mipmap GL_SGIS_texture_lod GL_SGIX_depth_texture
GL_SGIX_shadow GL_SUN_slice_accum

Program received signal SIGSEGV, Segmentation fault.
0x626f5f72 in ?? ()
(gdb) bt
#0  0x626f5f72 in ?? ()
Cannot access memory at address 0x65666675


Doh :/ I'll have to run gdb with a breakpoint then.





And that was one of the most interresting gdb run I've ever done. The game
crashes as soon as I run the line 2856 of gropengl.cpp
	mprintf(( "Extensions : %s\n", glGetString(GL_EXTENSIONS) ));

and if I just comment that line, it works perfectly ! If I step into, I arrive
in the function outwnd_printf2 with a tmp of size MAX_LINE_WIDTH*4 with
MAX_LINE_WIDTH=128 ! It seems the extensions available on the latest OpenGL
driver takes too much place even for that. I'll just increase it to 256 I
guess.
