Shader crash on 4th-5th gen GPUs

Michael_B_14 — Wed, 17 Jun 2015 16:34:44 GMT

Hey, I'm writing shaders in opengl 1.20 for a mod for minecraft which allows the usage of shaders.
However those shaders crash/fails to compile on 4th and 5th gen chipsets with drivers newer than .4080.
They work absolutely fine when using .4080.

Tested on:
Intel HD 4600, every driver after 4080 crashes / fails to compile the shaders
Intel HD 5500, every driver after 4080 crashes / fails to compile the shaders

OS:
Windows 7 x64 SP1
(OS doesn't seem to matter tho)

Crash doesn't occur on 2nd nor 3rd gen chipsets.
Tested on:
Intel HD 4000, driver 4226
Intel HD Graphics (bay trail mobile), driver 4226

Intel HD 4600 logs can be found here:

Shaders Files causing the crash/error during compiling can be found here:

Most of the time its the following code that causes the errors:

const ivec4 ToD[25] = ivec4[25](ivec4(0,200,134,48), //hour,r,g,b
                               ivec4(1,200,134,48),

Hi Michael,

I am talking with our OpenGL driver development team about this issue. The driver teams are very busy right now so it will take some time to get this properly debugged.

Hi Michael,

We found the problem causing your issue and has fixed it in out driver. The next HSW/BDW graphics driver release will have the fix.
