[Bug fortran/68155] ICE on initializing character array in type (len_lhs <> len_rhs)

--- Comment #2 from Gerhard Steinmetz <gerhard.steinmetz.fortran@t-online.de> ---
Fails (again len_lhs <> len_rhs) :

$ cat z3t.f90
program p
   type t
      character(2) :: z(1) = 'ab' // ['y']
   end type
   type(t) :: z
   print *, z
end

$ gfortran -g -O0 -Wall -fcheck=all z3t.f90
z3t.f90:3:28:

       character(2) :: z(1) = 'ab' // ['y']
                            1
Warning: CHARACTER expression at (1) is being truncated (3/2)
[-Wcharacter-truncation]
f951: internal compiler error: Segmentation fault

Again, works without type :

$ cat z3c.f90
program p
   character(2) :: z(1) = 'ab' // ['y']
   print *, z
end

$ gfortran -g -O0 -Wall -fcheck=all z3c.f90
z3c.f90:2:25:

    character(2) :: z(1) = 'ab' // ['y']
                         1
Warning: CHARACTER expression at (1) is being truncated (3/2)
[-Wcharacter-truncation]

$ a.out
 ab

Eventually one of the recent patches cures this one too.
