This happens in the stress test. Not sure why yet. Still investigating.

I figured it out. This failing has nothing to do with the C++ code. It is becase
F.p.name is non writable so line 993, 994, 995 do not create an own property.
The we hit line 996 and create a non configurable property. Yikes.

I'll black list Function name and write a dedicated test for it instead.
