The following program gives an ICE, which is maybe not surprising as deferred-length components are not yet supported. internal compiler error: in gfc_get_derived_type, at fortran/trans-types.c:2394 Expected: - Short term: Reject it ("sorry not yet implemented") - Long term: Support it. character(len=42), target, save :: A type :: t character(len=:), pointer :: P => A end type t type(T) :: X end

The ICE is fixed - but deferred-length character components are not supported: Instead of an internal compiler error, one now gets a "not yet implemented" error. Its implementation of is now tracked at PR 51976. *** This bug has been marked as a duplicate of bug 51976 ***
