[Bug middle-end/35099] [4.3 Regression] ICE in remove_unreachable_regions with -O -fopenmp

[rguenth at gcc dot gnu dot org]

------- Comment #4 from rguenth at gcc dot gnu dot org  2008-02-06 20:58 -------
Confirmed.

If you remove the second #pragma omp single in

      if( s == 0 ) {
#pragma omp single
#pragma omp single
        {
          for( LearnerBase * i = learners[0]; s == 0; ) {
            if( os ) i->getInfo();
          }
        }

then the ICE is gone.  It also warns about this, but I don't see this
warning in the original testcase, so the reduced testcase may not
trigger exactly the same bug - who knows.
