           Summary: OpenMP error message when compiling OpenACC code
           Product: gcc
           Version: 9.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

Hello,

When compiling the code below, the compiler generates error messages about
OpenMP syntax errors, but the code only uses OpenACC pragmas.
Also I think the code should compile and work fine.

I'm using GCC 9.1 with Power8 CPU

main.f:
      program main
      type t
        integer, allocatable :: inside(:)
      end type t

      type(t) :: my_t
      integer :: i
      allocate(my_t%inside(100))
!$acc enter data copyin(my_t, my_t%inside)
!$acc parallel loop present(my_t, my_t%inside)
      do i=1,100
        my_t%inside(i) = i
      end do
!$acc exit data copyout(my_t%inside, my_t)

      write(*,*)my_t%inside
      end program main

Compiling with:
gfortran main.f -Wall -Wextra -fopenacc

Error messages:
main.f:9:34:

    9 | !$acc enter data copyin(my_t, my_t%inside)
      |                                  1
