            Bug ID: 114815
           Summary: internal compiler error: Segmentation fault -
                    Segmentation Fault - on creating type with len
                    parameter and dependent on it character array
           Product: gcc
           Version: 13.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dencraft29 at gmail dot com
  Target Milestone: ---

The following code lets gfortran crash: 

program lab_1_4
    type Student_Group(Size)
        integer, len :: Size
        character :: Genders(Size) = ""
    end type Student_Group

    type(Student_Group(22)) :: Group
end program lab_1_4

I have this crash on both my systems:
- GNU Fortran 12.2.0 on Debian 12 (bookworm) 6.1.0.-17-amd64 (virtual machine)
- GNU Fortran 13.2.0 on MacOS on Apple M1 Sonoma 14.4.1 (Homebrew GCC 13.2.0)

When I compile file with provided code, it consistently results in a
segmentation fault. It doesn’t matter what compilation flags I set, it
reproduced always.
