[Bug fortran/29941] New: gfortran reports error with len of assumed size character array

["william dot mitchell at nist dot gov" <gcc-bugzilla at gcc dot gnu dot org>]

With this subroutine:

subroutine whatever(str)
character(len=*), dimension(*) :: str
integer :: i
i = len(str)
end subroutine whatever

gfortran reports:

i = len(str)
       1
Error: The upper bound in the last dimension must appear in the reference to
the assumed size array 'str' at (1)

The subroutine is valid -- you can pass an assumed size whole array to any
subroutine that does not need to know the shape of the array, and len can
accept either a scalar or an array.

The subroutine compiles if either an explicit length is given, i.e.
character(len=10), or the array is assumed shape, i.e. dimension(:).
