For the program, gfortran ICEs with:
f951: internal compiler error: in find_typebound_proc_uop, at
fortran/class.c:660
The failing assert is:
gcc_assert (derived->f2k_derived);
Note: The original test case (see link) misses an IMPORT, cf. PR 44614.
The additional derived type is required -- and for the ICE it needs to come
before the actual definition, otherwise, it works.
module factory_pattern
implicit none
type First_Factory
character(len=20) :: factory_type
class(Connection), pointer :: connection_type
contains
end type First_Factory
type, abstract :: Connection
contains
procedure(generic_desc), deferred :: description
end type Connection
abstract interface
subroutine generic_desc(self)
import ! Required, cf. PR 44614
class(Connection) :: self
end subroutine generic_desc
end interface
end module factory_pattern
