It's an interesting approach.  Have you considered an approach more
like Dejagnu's dg support?  It would be harder to write tests, but
would permit testing debugging info less invasively.

int
main (int argc, char *argv[])
{
  int i = argc+1;
  int j = argc-2;
  int k = 5;

  /* { gualchk argc  1 } */
  /* { gualchk i 2 } */
  /* { gualchk j -1 }  */
}
