   9 ! PR25625 - would neglect to point out that there were 2 subroutines p.
  10 module m
  11   implicit none
  12 contains
  13
  14   subroutine p (i)   ! { dg-error "(1)" }
  15     integer :: i
  16   end subroutine
  17
  18   subroutine p (i)   ! { dg-error "is already defined" }
  19    integer :: i   ! { dg-error "Unexpected data declaration statement in CONTAINS section" }
  20   end subroutine  ! { dg-error "Expecting END MODULE statement" }
  21 end module

  23 ! PR25124 - would happily ignore the declaration of foo in the main program.
  24 program test
  25 real :: foo, x
  26 x = bar ()          ! This is OK because it is a regular reference.
  27 x = foo ()
  28 contains
  29     function foo () ! { dg-error "explicit interface from a previous" }
  30       foo = 1.0  ! { dg-error "Unexpected assignment statement in CONTAINS section" }
  31     end function foo ! { dg-error "Expecting END PROGRAM statement" }
  32     function bar ()
  33       bar = 1.0
  34     end function bar
  35 end program test
