Bug ID: 110421
Summary: internal compiler error: in gfc_get_symbol_decl, at
fortran/trans-decl.cc:1548
Product: gcc
Version: 13.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gronki at gmail dot com
Target Milestone: ---
Reporting an ICE I encounter.
Test code:
program main
implicit none
type :: typ1
integer :: i
end type
type, extends(typ1) :: typ1a
end type
type :: typ2
class(typ1), allocatable :: t1
end type
type(typ2) :: t2
! works
t2 = typ2(t1=typ1(1))
! crash
t2 = typ2(t1=typ1a(1))
end program
Error:
gfortran -v -save-temps test.f90
Driving: gfortran -v -save-temps test.f90 -l gfortran -l m -shared-libgcc
