[Bug fortran/68225] ICE with -Wrealloc-lhs-all on structure constructor with allocatable components

[gerhard.steinmetz.fortran@t-online.de]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68225

--- Comment #1 from Gerhard Steinmetz <gerhard.steinmetz.fortran@t-online.de> ---
Adding one type extension :

$ cat z0.f90
program p
   type t
      integer, allocatable :: a
   end type
   type, extends(t) :: t2
      integer, allocatable :: b
   end type
   type(t2) :: x
   x = t2()
   print *, allocated(x%a), x%a
   print *, allocated(x%b), x%b
end


$ gfortran -g -O0 -Wall -Wrealloc-lhs-all z0.f90

z0.f90:9:0:

    x = t2()
 1
in gfc_format_decoder, at fortran/error.c:1124


---

$ gfortran -g -O0 -Wall -fcheck=all z0.f90
$ a.out
 F           0
 T           0


Note that allocation status is different.
