[Bug libfortran/33672] New: Additional runtime checks needed for namelist reads

["jvdelisle at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

As discussed on comp.lang.fortran.  The test case namelist_15.f90 has three
examples of invalid derived type specifiers.  Only one none-zero rank object is
allowed.

>   write (10, '(A)') " x%i = , ,-3, -4"

The line above is illegal. It represents an array of arrays (i and m), which 
is not allowed in Fortran (see "Fortran 95/2003 Explained", Section 6.13).

> >   write (10, '(A)') " x(2)%m(2)%ch(1)(1) ='w',"

This line contains a spurious '(1)'

> >   write (10, '(A)') " x%m%ch(:)(2) = 'z','z','z','z','z','z','z','z',"

This is also an attempt at an array of arrays (x and m).

Thanks to Mike Metcalf for clarifications.  See the book.
