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.
