[Bug fortran/82904] ICE in make_ssa_name_fn, at tree-ssanames.c:261

--- Comment #1 from G. Steinmetz <gscfq@t-online.de> ---

Without this explicit "save" in above source, an ICE only occurs with
additional option -fno-automatic (which implies "save") :


$ cat z2.f90
program p
   character(:), allocatable :: x
   character(:), allocatable :: y[:]
   allocate (character(3) :: y[*])
   allocate (x, source='abc')
   y[1] = x
end


$ gfortran-8-20171105 -O2 -c z2.f90 -fcoarray=lib
$
$ gfortran-8-20171105 -O2 -c z2.f90 -fcoarray=lib -fno-automatic
during IPA pass: inline
z2.f90:7:0:

 end
