I know strange params, but still:

$ cat unpack.f90
   type i4_t
      integer v
   end type 
   type(i4_t), dimension(3,3) :: bt4
   if (any (bt4v .ne. reshape ((/1, 2, 0, 3, 1, 0, 0, 0, 4/), (/3, 3/)))) bt4%v
= 1
   if (any (bt4%v .ne. reshape ((/0, 2, 0, 3, 0, 0, 0, 0, 4/), (/3, 3/)))) STOP 
end 

$ gfortran unpack.f90 --param=max-completely-peeled-insns=0
-fno-tree-dominator-opts --param=unroll-jam-min-percent=0 -fno-tree-ch -O3 -c
during GIMPLE pass: unrolljam
