In fcl-passrc, PasWriter.WriteModule is unable to show programs with label declarations and statement with label marks

In fcl-passrc, PasWriter.WriteModule is unable to show programs with label declarations. Moreover, it can't diplay statements with label marks.

For example:

program Prog;
{$mode ObjFpc}

label
  Here;

begin
  writeln;
Here :
  writeln;
  Goto Here;
  writeln;
end.

With the above example, an exception is raised.
