--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
It actually fails in the same way with "-fopenmp" and 'acc' replaced by 'omp':

long long n = 100;
void test1(int x, double *a, double *b, double *c, double *totals)
{
#pragma omp atomic capture
      c[x] = totals[x%((int)(n/10 + 1))] = (a[x] + b[x]) + totals[x%((int) n/10
+ 1)];
}


I also missed to include the invoking part of the of stacktrace:
