Only the module is needed to reproduce the bug:
module helper
   implicit none
   contains
      function dud(x)
         integer, intent(in) :: x
         character(selected_int_kind(x)+2) dud

         dud(1:1) = 'c'
      end function dud
end module helper

Here's a similar testcase that crashes in the same spot:

======================================
module FOO
contains
    function BAR(X)
        character(*)      :: X
        character(len(X)) :: BAR
        BAR = 'c'
    end function
end

PR 15326 will not be fixed for 4.0, I presume, so neither will this. Thus I
consider this as fixed it is going to get.

Fixed on 4.1.  Not yet fixed on 4.0, because it depends on PR 15326 which
hasn't been fixed for 4.0.

        * trans-decl.c (gfc_finish_var_decl): Add decl to the
        current function, rather than the parent.  Make
        assertion accept fake result variables.
        * trans-expr.c (gfc_conv_variable): If the character
        length of an ENTRY isn't set, get the length from
        the master function instead.
