OpenGL bindless texture crash in driver 24.10.1

OpenGL bindless texture crash in driver 24.10.1
In driver 24.10.1 it seems that calls to textureQueryLevels and textureSize using samplers from bindless texture handles cause a crash. No OpenGL errors are reported. My previous driver version 24.7.1 had no such problems with the same code.
 
 
In Shaders/PBR/Lighting.glsl:

 

 

u_MipCount = textureQueryLevels(samplerCube(specularmap));

 

 

In Shaders/Base/Lighting.glsl:

 

 

float sz = 1.0f / float(textureSize(shadowmap, 0).x);

 

 

Note that the code doesn't even get executed, but its presence in the shader is enough to cause the crash.
