One test fails and three timeout with OpenMP enabled

[penguinpee]

I have packaged omega_h for Fedora since STEPS depends on it.

When I enable Omega_h_USE_OpenMP I noticed that tests take much longer to complete. But, more important, with OpenMP reverse_class_test fails and three other tests (warp_test_parallel, rc_field_test and rc_field_testp) timeout.

Without OpenMP all tests succeed.

The failing test leaves the following entry in the build log:

22/29 Test #26: reverse_class_test ...............***Failed    1.50 sec
assertion face_rc.ab2b == LOs({0, 1, 2, 3, 4, 5}) failed at /builddir/build/BUILD/omega_h-10.1.0/src/reverse_class_test.cpp +24

This typically refers to a problem with your application.
Please see the FAQ page for debugging suggestions

I also tried with Omega_h_THROW enabled in the hope that this would give me some more info when the test crashes, but it just changes the assertion line to:

terminate called after throwing an instance of 'Omega_h::exception'
  what():  assertion face_rc.ab2b == LOs({0, 1, 2, 3, 4, 5}) failed at /builddir/build/BUILD/omega_h-10.1.0/src/reverse_class_test.cpp +24

The full log is available online. You may wanna search for EXIT CODE: 134. The actual testing starts at ^Executing(%check):.

Let me know what other information you may need.
