--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to Richard Biener from comment #5) > The issue here is the induction variable is shared? Ah right, the testcase is clearly invalid. There is a data race on i, as well as data races on all the a[i] stores (because 4 different threads all do the same thing). Andi, did you mean #pragma omp parallel for num_threads(4) instead?
