BTW, using + reduction in the same loop (and with asm optimization barrier for
that variable) I see the reduction computed value always correct, so the loop
body is executed the correct number of times. That means in some cases the
memory reads/writes between GOMP_atomic_{start,end} must overlap between
threads.-- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37938
