Are you using trunk versions of both clang and libomp? I only use the check-libomp target now in CMake and don't see any problems with the trunk version of libomp on Darwin. Can you send me the source file for orph_test_omp_parallel_copyin.c and I'll take a look at it.

Is anyone else seeing segfaults in the orph_test_omp_parallel_copyin test case from the OpenMP3.1_Validation test suite? On x86_64-apple-darwin15, todays trunk produces,,,
Jacks-Mac-Pro:c howarth$ clang-3.8 -fopenmp -O0 -g orph_test_omp_parallel_copyin.c -o orph_test_omp_parallel_copyin Jacks-Mac-Pro:c howarth$ lldb ./orph_test_omp_parallel_copyin
(lldb) target create "./orph_test_omp_parallel_copyin"
Current executable set to './orph_test_omp_parallel_copyin' (x86_64).
