--- Comment #9 from Gerhard Steinmetz <gerhard.steinmetz.fortran@t-online.de> ---
Another example, together with LANG=de_DE.UTF-8 :


$ cat zz1.f90
program p
   type t
      character, allocatable :: z1(:), z1(:)
   end type
end


$ gfortran-7-20161204 -m32 zz1.f90
zz1.f90:3:37-44:

       character, allocatable :: z1(:), z1(:)
                                     2      1
Error: Component »z1« at (1) already declared at (2)
