The attached program horribly crashes the GPU, X crashes and won't start again until next reboot

How reproducible:
Always

Steps to Reproduce:
1. Compile and run the attached program ("Shaders")
2. 
3.
  
Actual results:
Big crash

Expected results:
Should not crash

Additional info:
Without the codeblock at shaders/ex2.glslf::31-40, the program does not crash, hence it appears to be a problem with the glsl compiler.
Running on proprietary nvidia works fine.

Hm, the other one was a little huge, here is a stripped version with only the messages from the relevant session, sorry...
