Summary of Problem

Description:
I did try to build programs from GitHub - greensoftwarelab/Energy-Languages: The complete set of tools for energy consumption analysis of programming languages, using Computer Language Benchmark Game and when building with clang I receive following error.

binarytrees.chpl:75: internal error: RES-FUN-ION-2804 chpl version 2.5.0\nNote: This source location is a guess.\
