--- Comment #2 from janus at gcc dot gnu.org 2010-12-20 15:16:44 UTC --- (In reply to comment #0) > STORAGE_SIZE does not work for unallocated polymorphic types. However, the > Fortran 2008 standard allows them: > > "A shall be a scalar or array of any type. If it is polymorphic it shall > not > be an undefined pointer. If it has any deferred type parameters it shall > not be an unallocated allocatable variable or a disassociated or > undefined > pointer." (F2008, 13.7.160) I don't really understand this. Why should one allow it for unallocated allocatables, but not for undefined pointers? Also, it's not exactly clear to me which value to expect for such a case. From the standard's description of STORAGE_SIZE: "The result value is the size expressed in bits for an element of an array that has the dynamic type and type parameters of A." However, if A is unallocated, it does not have a dynamic type!
