[Bug fortran/35131] New: OpenMP: Private variable passed to subroutine

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

As reported by Ignacio Fernández Galván, the following program prints with
"gfortran -fopenmp" 0.0 instead of 42.0. Without -fopenmp or using, e.g., ifort
or sunf95 42.0 is printed.

See also http://gcc.gnu.org/ml/fortran/2008-02/msg00058.html

I believe the program is valid, compare also

PROGRAM Outer
 IMPLICIT NONE
 REAL, DIMENSION(20) :: A
 INTEGER :: k
 A = 0.0
!$OMP PARALLEL DO PRIVATE(k)
 DO k=1,SIZE(A)
   CALL Inner(k)
 END DO
!$OMP END PARALLEL DO
 print *, A
CONTAINS
 SUBROUTINE Inner(i)
   IMPLICIT NONE
   INTEGER :: i
   A(i) = 42
 END SUBROUTINE Inner
END PROGRAM Outer
