Log
When trying to start the tutorial in today's version of Dota 2, there's a
segfault in check_begin_texture_render():
Program received signal SIGSEGV, Segmentation fault.
0xf5397c5a in check_begin_texture_render (ctx=0x8bb4000, fb=0x17e90700)
at ../../src/mesa/main/fbobject.c:1871
1871 if (att->Texture && att->Renderbuffer->TexImage) {
(gdb) p *att
$3 = {Type = 5890, Complete = 0 '\000', Renderbuffer = 0x0,
Texture = 0x17e88500, TextureLevel = 0, CubeMapFace = 0, Zoffset = 0,
Layered = 0 '\000'}
att->Renderbuffer is dereferenced even though it's null.
I can reproduce this segfault reliably with Mesa git-e4fdf1b on my rv730.
The log I'm attaching shows a bunch of messages like
<span class="quote">> ##### CMaterialReference::Init got error material for dev\white in tex group Other textures</span >
that might be related.</pre>
