Using same name for procedure and its argument leads to wrong code

[wipe2238]

procedure stuff(variable stuff, variable in_recursion := 0)
begin
  if not(in_recursion) then
   stuff := stuff(stuff, 1);
  else
  begin
     display_msg("doing critical stuff");
     stuff++;
     return stuff;
  end
end

procedure start begin call stuff(0); end

According to int2sll it compiles to

procedure stuff(variable arg0, variable arg1);
procedure start;

procedure stuff(variable arg0, variable arg1)
begin
    if (not(arg1)) then begin
        arg0 := arg0(arg0, 1); // wait what...
    end
    else begin
        display_msg("doing critical stuff");
        arg0 := arg0 + 1;
        return arg0;
    end
end

procedure start
begin
    call stuff(0, 0);
end
