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.
