Description Tobias Burnus 2007-02-23 21:24:28 UTC 
NAG f95:
Error: bar.f90, line 6: Array supplied for dummy IN (no. 1) of COPY too small
g95:
Error: Array argument at (1) is smaller than the dummy size
gfortran: No error/warning.

--------------------------
program main
implicit none
character :: digit_arr(10)
call copy(digit_arr)
contains
  subroutine copy(in)
    character, dimension(11) :: in, out
  end subroutine copy
end program main
--------------------------

Note: The other way round is ok, i.e. actual = 1:10, dummy = 1:8

Related to -fbounds-check, isn't it?

> Related to -fbounds-check, isn't it?
As my initial bug is fixed:

Warnung: Actual argument contains too few elements for dummy argument 'in' (10/11) at (1)

and the missing parts are in PR30939, I dedicate it to the run time test.

Test: Place program and subroutine in different files, compile and run them. NAG f95 -C=all shows then:


Actual argument for dummy array IN too small -
10 elements instead of 11
Program terminated by fatal error
In COPY, line 1 of aa.f90
Called by MAIN, line 4 of ab.f90

Same as PR27989.
