This seems to work for me now
jh@gcc10:~/trunk/build/gcc$ ./gfortran -O2 -c t.f90 -B ./
jh@gcc10:~/trunk/build/gcc$ cat t.f90
SUBROUTINE goo()
IMPLICIT NONE
CHARACTER(len=9),SAVE :: s
INTEGER,SAVE :: i,j,k
i=0
j=0
DO WHILE (i==0)
   CALL goo1(s)
   IF (INDEX(s,'$')/=1 .AND. INDEX(s,'!')/=1) THEN
      CALL goo2(k)
      IF (k>0) THEN
         i=1
      END IF
   END IF
END DO
END SUBROUTINE
! gfortran -O2 -c goo.f90

(similarly with the C testcase).  It would be nice to know what fixed it. H.J,
do you think you can track it?
