             Bug #: 55282
           Summary: openmp directive and classes
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: valeryweber@hotmail.com


Dear All

The following code doesnt compile at all with the lattest gfortran.=20
The problem seems to be in the class definition of the variable "this"=20
(works fine while declared as type).

gcc version 4.8.0 20121112 (experimental) (GCC)=20

>>>>>
module mod
  use omp_lib
  type :: my_t
     integer :: i
  end type my_t
contains
  subroutine init( this )
    class( my_t ) :: this
!    type( my_t ) :: this
    write(*,*) 'init thread=3D',omp_get_thread_num()
    this%i=3D2
  end subroutine init
end module mod
program prog
  use mod
  type( my_t ) :: a
!$omp parallel default( none ) &=20
!$omp          private( a ) &=20
!$omp          num_threads( 4 )
  call init(a)
!$omp end parallel
end program prog
