--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
The function is

PROCEDURE KeyPressed () : BOOLEAN ;
BEGIN
   IF rStack=3DNIL
   THEN
      Halt(__FILE__, __LINE__, __FUNCTION__, 'no active status procedure')
   ELSE
      RETURN( rStack^.s() )
   END
END KeyPressed ;


I'm not sure how the middle-end diagnostic issued from CFG build is confused
here though, I'm not yet familiar with using cc1gm2 to debug things, nor
produce standalone modula-2 testcases ;)

It also means people might see bogus diagnostics for code like this.=
