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

AFAICT -fwhole-file is enough to get the ICE: '-O2 -fipa-cp-clone
-ftree-vectorize -fno-signed-zeros -fno-trapping-math -fassociative-math
-fwhole-file'.
