A localparam of unpacked array type isn't considered const in this example and also fails to be handled in the SimulateVisitor:

module top;
  function integer get_element;
    input integer index;
    input integer array_arg[7:0];
    get_element = array_arg[index];
  endfunction

  localparam integer array[7:0] = '{12, 12, 12, 12, 12, 12, 12, 12}; // line 8
  localparam element = get_element(0, array);                        // line 9
endmodule

Produces:

%Error: a.v:9: Expecting expression to be constant, but variable isn't const: array
%Error: a.v:9: Expecting expression to be constant, but can't determine constant for FUNCREF 'get_element'
%Error: a.v:8: ... Location of non-constant INITARRAY: Unknown node type, perhaps missing visitor in SimulateVisitor
