Bug in GLSL compiler?
First of all I beg pardon if I post to the wrong forum, but I couldn't find anything more specific.
I'm writing an application that uses GLSL fragment shaders. I found that the driver crashes when glUniform1ivARB() is invoked for arrays of sampler2D variables.
I tried a similar shader in ShaderDesigner (freeware, can be downloaded here: http://www.typhoonlabs.com/) and the program exhibits quite a similar crash. Here's a simple fragment shader that will crash if you try to set the tex array from C:
Is there any chance this will be fixed someday?

Re: Bug in GLSL compiler?
I've used an array of shadowmaps with success on Quadro FX 4500,5500,4600 & 5600 cards.
#define NUMLIGHTS 8
uniform sampler2DShadow depthTex[NUMLIGHTS];
uniform mat4 cn_ShadowMat[NUMLIGHTS];
uniform float cn_ShadowSize[NUMLIGHTS];
