--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
No idea where you got that #pragma omp atomic should be sequentially
consistent, it is relaxed.  OpenMP 4.0 introduces seq_cst clause on all the
#pragma omp atomic {,update,read,write,capture} variants that makes it
sequentially consistent.
