Fireflies on CoronaLight mat in constant mode on thin geometry
Why appears fireflies on CoronaLight material in Constant mode on thin geometry? This is shader core limitations? Because scene don't have GI.

Are those NaNs/INFs? can you send the scene?

yep, this is the traditional problem with selfintersections/leaks. Your geometry near the corners is extremely elongated, so there are some numerical issues. Setting embree triangles to precise seems to be helping with this scene a lot.
