Confirmed.  We ICE in the vectorizer SLPing.

Somewhat reduced testcase:

      SUBROUTINE XSHOW(MAASY,MBASY,MCASY,NAASY,NBASY,NCASY,
     &      XRMREF,XRNSYM2,XRSYMM2,XRITSY2,MBINS)
      INTEGER HEAPDM
      PARAMETER (HEAPDM=2)
      INTEGER HEAP(HEAPDM)
      INTEGER HPMXUS
      INTEGER HPCURR
      COMMON // HEAP, HPMXUS, HPCURR
      CHARACTER*2 TYPE, TYPE2, DOMAIN, DOMAIN2
      CHARACTER*4 SHOW
      DOUBLE COMPLEX SHOW1,SHOW2
      INTEGER VLEVEL, DEPTH
      DO WHILE (START.LE.STOP)
      CALL XMDOMAK(A,B,C,HEAP(INDEXA),HEAP(INDEXB),HEAP(INDEXC),
     & HEAP(INDEXA),HEAP(INDEXB),HEAP(INDEXC),XRNSYM)
      CALL XMDOSHO(SHOW,SHOW1,SHOW2,NSHOW,TYPE,VLEVEL,DEPTH,NSELE,
     & HEAP(VSTACK),HEAP(LSTACK),
     & MAASY,MBASY,MCASY,NAASY,NBASY,NCASY,
     & HEAP(HPRHOMA))
      END DO
      END
      SUBROUTINE XMDOSHO(SHOW,SHOW1,SHOW2,NSHOW,TYPE,
     &                   VLEVEL,VMAX,N,VSTACK,LSTACK,
     &                   MAASY,MBASY,MCASY,NAASY,NBASY,NCASY,RHOMASK)
      CHARACTER*(*) SHOW
      DOUBLE COMPLEX SHOW1, SHOW2
      CHARACTER*(*) TYPE
      INTEGER VLEVEL, VMAX, N
      DOUBLE COMPLEX VSTACK(N,VMAX)
      DOUBLE COMPLEX LSHOW1
      DO I=1,N
      LSHOW1=LSHOW1+VSTACK(I,VLEVEL)
      END DO
      SHOW1=LSHOW1
      END
