Reduced testcase:

module test
  implicit none

  interface operator(.foo.)
     module procedure b_op_a
  end interface operator(.foo.)

  contains

     function a_op_b()
        integer, intent(in) :: a, b
        integer :: a_op_b, b_op_a
     entry b_op_a(a,b)
     end function a_op_b

end module test

$ gfortran -c a.f90 
a.f90:13.17:

     entry b_op_a(a,b)
                1
Internal Error at (1):
