A weird crash in Partha's build, can't reproduce in ion12's build

Can’t reproduce these crashes on ion12’s build from here:

That’s great. We are also trying to solve some old clang related restrictions. That would speedup denoise for rt clang builds!

I brought this quote over from the previously resolved thread.
Regarding @ion12’s build I noticed it uses clang3.9, partha uses cc and I was trying and failing on Apple LLVM version 8.0.0 (clang-800.0.42.1)
I was leaving out the clang3.9 from the macport script in the rawpedia because it always crashed when trying to compile. I believe the system has a more modern clang that is unable to compile the source code as it is now, is that accurate to say?
