The following is also not caught:
-----------------------------
        subroutine foo(y)
           character(len=20) :: y
           y = 'hello world'
        end

        program test
           character(len=10) :: x
           call foo(x)
           write(*,*) 'X=',x
           pause
        end
-----------------------------

NAG's f95 spits out this error:
Error: test17.f90: Argument Y (no. 1) in reference to FOO from TEST is too
short a character string
