[Bug fortran/27161] New: -fbounds-check is too strict for assumed size arrays

[schnetter at aei dot mpg dot de]

The following programme

program checkarrsize
  implicit none
  double precision a(10,10)
  call sub (a)
contains
  subroutine sub(a)
    double precision a(*)
    a(20) = 0
  end subroutine sub
end program checkarrsize

passes a two-dimensional array to a subroutine that expects a one-dimensional
assumed size array.  When I compile this with

$ ~/gcc/bin/gfortran --version
GNU Fortran 95 (GCC) 4.2.0 20060329 (experimental)

$ ~/gcc/bin/gfortran -fbounds-check -o checkarrsize checkarrsize.f90 

and run it, then I receive the run-time error message

$ ./checkarrsize 
Fortran runtime error: Array reference out of bounds
