This should be addressed for the 3.2 release, otherwise the 3.2 release will crash on some machines with Intel graphics. (Blender dereferencing a NULL pointer from a failed shader compilation)

Stefan Werner (swerner) added a comment to D14058: Cycles: Removed redundant/buggy code in multiscatter BSDF.

float3 wr = -wi;
followed by
normalize(wi + wr)
inevitably causes a division by zero. In this instance, it means that throughput is (1, 1, 1) at all times, making the call to interpolate_fresnel_color() redundant.
