            Bug ID: 67311
           Summary: ICE calling subroutine with derived type as argument
                    within OpenMP parallel region
           Product: gcc
           Version: 5.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: acreman at astro dot ex.ac.uk
  Target Milestone: ---

The following test case produces an internal compiler error with recent
gfortran versions:

! == Begin test case ==
subroutine test
  call openmp_sub
end subroutine test

subroutine openmp_sub

  implicit none

  TYPE myType
    TYPE(myType), DIMENSION(:), POINTER :: x
  END TYPE myType

  type(myType) :: argument
!$OMP PARALLEL DEFAULT(NONE) PRIVATE(argument)
  call foo(argument)
!$OMP END PARALLEL

end subroutine openmp_sub
! == End test case ==

The command line used to build was:  gfortran -c -fopenmp test.f90
I see an ICE at versions 4.9.3 and 5.2 on SLES and gfortran 4.9.2 on Mac OS. 
The test case compiles OK with version 4.6.3 (SLES) and 4.8.2 (Ubuntu)

The output from gfortran 4.9.3 is: 

> gfortran -c -fopenmp test.f90
gfortran: internal compiler error: Segmentation fault (program f951)
