           Summary: ICE on return of derived type with allocatable-length
                    character component
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

A more involved example that is closer to the intended use.

gfortran 4.6 give an ICE on the code below (and on the attached more involved
example):

$ cat message.F90
module message_module
  type message
    character(:) ,allocatable :: string
  end type
contains
  type(message) function new_message()
  end function
end module

$ gfortran -c message.F90
message.F90:6:0: internal compiler error: in gfc_get_derived_type, at
fortran/trans-types.c:2298
Please submit a full bug report,
with preprocessed source if appropriate.

I don't know where I grabbed your code, but I have already opened pr47545 for
it. Comment #2 says

> Deferred-length components are not yet supported, cf. bug 45170 comment 9.
>
> Nevertheless, gfortran should not ICE.
