Hit while trying out the r300g driver by playing Oolite (svn HEAD, no OXPs
needed, but shaders turned up to full).

Setup: Debian testing/unstable, with bits from experimental.
  xserver-xorg-core 1.7.5
  xserver-xorg-video-radeon 6.12.192-1
  libdrm 2.4.19 (local build, with packaging adapted from 2.4.18-4)
  mesa git 2ad8692a (local build, with packaging adapted from 7.7-4)

Reverting cba6430524198a1bdcdeada03cbe946a454f3935 stops the hardlock, but now
there's a failing vertex shader. Looking into it now.

Tired, commented on wrong bug. Investigating yours now.

Can't figure out how to build your program. :T

You hit the generic "error in shader compiler" assert. Could you run again with
RADEON_DEBUG=fp set, and attach that log here?

Created an attachment (id=34486)
 --> (http://bugs.freedesktop.org/attachment.cgi?id=34486)
Shader log from Oolite

One log file, as requested. (This is with shader-effects-level set to 3.)

About compiling Oolite: "make -f Makefile pkg-deb" works here. ("debuild
binary" would be fine, but debian/changelog is generated.)

http://www.oolite.org/download has links to binaries.

I won't be able to reproduce exactly, without finding one of my older cards.
Also oolite appears to refuse to enable fancy shaders. :T

Basically, the shader is too big for the hardware. There's no obvious
optimizations to be done, but I bet I could find some, if the shader is known
to work on fglrx.

I've pushed a patch to make it so that you get an error message instead of just
an empty assertion.
