* [Bug fortran/41582] New: Allocation of abstract types requires a type spec or a SOURCE @ 2009-10-05 12:53 burnus at gcc dot gnu dot org 2009-10-08 15:39 ` [Bug fortran/41582] " burnus at gcc dot gnu dot org ` (2 more replies) 0 siblings, 3 replies; 4+ messages in thread From: burnus at gcc dot gnu dot org @ 2009-10-05 12:53 UTC (permalink / raw) To: gcc-bugs type, abstract :: t end type t class(t), allocatable :: a allocate(a) is wrong. For the allocate one has to use either allocate(derived-type :: a) or allocate(a, source=some_type_or_class) One needs to reject this at compile time. * * * Another interesting issue is: type, abstract :: t end type t class(t), allocatable :: a,b allocate(a, source=b) end That is invalid as "b" is not allocated, i.e. it does not have a dynamic type. A check could/should be implemented at the same time as PR 41581. -- Summary: Allocation of abstract types requires a type spec or a SOURCE Product: gcc Version: 4.5.0 Status: UNCONFIRMED Keywords: accepts-invalid Severity: normal Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: burnus at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41582 ^ permalink raw reply [flat|nested] 4+ messages in thread
