This is with GNU Fortran 95 (GCC) 4.2.0 20060608 (experimental) and 4.1.0 (SUSE
Linux).

The following program has a problem as the passed array is shorter than the
array expected by the subroutine. Currently, gfortran does not detect this
problem.

Expected: Something like
  Actual argument for dummy array A too small - 3 elements instead of 5
(this is the NAG -C=all output)

----------<cut>-----------
program test
  implicit none
  real :: b(3)
  b = 42.0
  call sub(5,b)
end program test

subroutine sub(n,a)
  implicit none
  integer, intent(in) :: n
  real, intent(in) :: a(n)
  print *,a
end subroutine sub
-------<cut>----------------

This should probably marked as blocking -fbounds-check meta bug 27786.

------- Comment #2 from tobias dot burnus at physik dot fu-berlin dot de  2006-09-10 19:23 -------
Maybe this should not be done with -fbounds-check, but put into a different
option. (NAG uses not -C=array but -C=call for this.)

The reason is that some programs (e.g. Exciting.sf.net) passes an array(n-1) to
a subroutine foo(n,b) with "real :: b(n)" but only accesses the first n-1
elements.
