Worked: -

Short description of error
Sample file:
If I try to render this file with the 2.92 or more recent builds it crash.

Exact steps for others to reproduce the error

Render the file from within Blender (not via command-line). If I do it with my own debug build I get the following assert:

blender: intern/cycles/kernel/../kernel/kernel_subsurface.h:658: bool ccl::subsurface_random_walk(ccl::KernelGlobals*, ccl::LocalIntersection*, ccl::ShaderData*, ccl::PathState*, const ShaderClosure*, float, float): Assertion isfinite_safe(throughput.x) && isfinite_safe(throughput.y) && isfinite_safe(throughput.z)' failed.
