Hi,
the following (invalid) code gives an ICE:
module gfcbug95
implicit none
type, abstract :: vector_class
end type vector_class
type, extends(vector_class) :: trivial_vector_type
real :: elements(100)
end type trivial_vector_type
contains
subroutine bar (this,v)
class(trivial_vector_type), intent(inout) :: this
class(vector_class), intent(in) :: v
select type (v)
! class is (trivial_vector_type) ! OK
class is (bad_id) ! ICE
this%elements(:) = v%elements(:)
end select
end subroutine bar
end module gfcbug95
% gfc45 gfcbug95.f90
gfcbug95.f90:16.20:
class is (bad_id) ! ICE
1
Error: 'bad_id' at (1) is not an accessible derived type
f951: internal compiler error: Segmentation fault
Cheers,
-ha

Confirmed. The same happens for TYPE IS (bad_id).

------- Comment #3 from janus at gcc dot gnu dot org 2009-12-09 18:17 -------
Mine.
I think this one-liner is all that's needed:
Index: gcc/fortran/symbol.c
===================================================================
--- gcc/fortran/symbol.c (revision 155023)
+++ gcc/fortran/symbol.c (working copy)
@@ -2476,7 +2476,7 @@ select_type_insert_tmp (gfc_symtree **st)
{
gfc_select_type_stack *stack = select_type_stack;
for (; stack; stack = stack->prev)
- if ((*st)->n.sym == stack->selector)
+ if ((*st)->n.sym == stack->selector && stack->tmp)
*st = stack->tmp;
}
With this, the test case gives:
c0.f90:16.20:
class is (bad_id) ! ICE
1
Error: 'bad_id' at (1) is not an accessible derived type
c0.f90:17.36:
this%elements(:) = v%elements(:)
1
Error: 'elements' at (1) is not a member of the 'vector_class' structure
