[Bug c/21985] New: miscompiled or wrong code snippet?

["marcus at jet dot franken dot de" <gcc-bugzilla at gcc dot gnu dot org>]

Hi,  
  
the attached code compiles fine and does calculate the offset between  
the current stackpointer and the passed point in gcc versions before 4.0.  
  
In 4.0 the expression is reduced to -16384 even in the t03.generic dump  
which makes me suspect a parser problem.  
 
Or it might just be wrong code... I am not sure.
