The fix for PR42521 produces an ICE in 434.zeusmp:
+ /home/seb/gcc/graphite/usr/bin/gfortran -c -g -O2 -DSPEC_CPU_LP64 -o pdv_d.o
pdv_d.f
pdv_d.f: In function pdv_d:
pdv_d.f:89:0: error: definition in block 40 does not dominate use in block 212
for SSA_NAME: prephitmp.28_439 in statement:
D.2771_606 = D.2770_605 <= prephitmp.28_439;
pdv_d.f:89:0: internal compiler error: verify_ssa failed

This is the reduced testcase:
parameter(in = 128+5
& , jn = 128+5
& , kn = 128+5)
real*8 d (in,jn,kn)
real*8 dcopy(in,jn,kn)
call pdv (is, dcopy)
do k=ks,ke
do j=je+1,je+2
do i=is-2,ie+2
dcopy(i,j,k) = d(i,j,k)
enddo
enddo
enddo
do k=ks,ke
do j=js,je
do i=is-2,is-1
dcopy(i,j,k) = d(i,j,k)
enddo
