!This benchmark is extracted from flush_nolist.1c of OpenMP Application
!Programming Interface Examples Version 4.5.0 .
!We added one critical section to make it a test with only one pair of data races.
!The data race will not generate wrong result though. So the assertion always passes.
!Data race pair:  i@37:13 vs. i@38:15
