Short description of error
Load the following file and click "bake indirect lighting." It will crash in eevee_subsurface.c:EEVEE_subsurface_add_pass. "psl->sss_blur_ps" is NULL. If you add a simple "if (!psl->sss_blur_ps) return;" it won't crash; interestingly enough, the compiler optimizes out the entire function. Anyway, that probably isn't the right fix.
