Bug #: 56845
Summary: [OOP] _vptr not set to declared type for CLASS + SAVE
Classification: Unclassified
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Keywords: wrong-code
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: bur...@gcc.gnu.org
CC: ja...@gcc.gnu.org
The program below fails at run time. Unallocated the class should match the
declared type - but it is never set with SAVE.
The dump of the following program shows:
static struct __class_m_T_a y = {};
Expected:
static struct __class_m_T_a y = { ._data = 0B, ._vptr = &__vtab_m_T};
module m
type t
integer ::a
end type t
contains
subroutine sub
type(t), save, allocatable :: x
class(t), save,allocatable :: y
if (.not. same_type_as(x,y)) call abort()
end subroutine sub
subroutine sub2
type(t), save, allocatable :: a(:)
class(t), save,allocatable :: b(:)
if (.not. same_type_as(a,b)) call abort()
end subroutine sub2
end module m
use m
call sub()
call sub2()
end
