The file in the attachment is called 'test_h5_attr.f90' and I don't find any
ASSOCIATE construct in there. Wrong file attached?

Ooops -- wrong test case. Here it is:

subroutine sub (x)

  implicit none

  real, intent(in) :: x

  !$omp single
  associate(x_a => x)
  end associate
  !$omp end single 

end subroutine sub

Note: OpenMP 3.1 does not handle any of Fortran 2003.

In the current draft of OpenMP 4.0 (RC2), cf.
http://openmp.org/wp/openmp-specifications/, many F03 features are still not
supported. However, ASSOCIATE actually seems to be supported.

--- Comment #4 from janus at gcc dot gnu.org ---
The final specification of OpenMP 4.0 has been published by now and apparently
supports the ASSOCIATE construct.

The test in comment 2 compiles with r206348. I doubt the fix (OpenMP 4.0?) will
be back ported to 4.8. Closing as FIXED?

The original test also compiles and runs with 4.9.0 and trunk (4.10, r210000).
No answer for more than three months. Closing as FIXED.
