--- Comment #2 from rwgk at yahoo dot com 2010-12-17 22:34:16 UTC ---
Using a binary search I found that svn rev. 161579 introduced the ICE.
(Note that I had to replace gcc/config/i386/i386.md with rev. 161594
since gcc doesn't build otherwise.)
% svn log -v -r 161579

Machinery to support implicit delete/move.
* cp-tree.h: (struct lang_type_class): Add lazy_move_assign,
has_complex_move_ctor, has_complex_move_assign bitfields.
(CLASSTYPE_LAZY_MOVE_ASSIGN): New.
(TYPE_HAS_COMPLEX_MOVE_ASSIGN): New.
(TYPE_HAS_COMPLEX_MOVE_CTOR): New.
(enum special_function_kind): Add sfk_move_assignment.
(LOOKUP_SPECULATIVE): New.
* call.c (build_over_call): Return early if it's set.
(build_over_call): Use trivial_fn_p.
* class.c (check_bases): If the base has no default constructor,
the derived one is non-trivial. Handle move ctor/op=.
(check_field_decl): Likewise.
(check_bases_and_members): Handle move ctor/op=.
(add_implicitly_declared_members): Handle CLASSTYPE_LAZY_MOVE_ASSIGN.
(type_has_move_constructor, type_has_move_assign): New.
* decl.c (grok_special_member_properties): Handle move ctor/op=.
* method.c (type_has_trivial_fn, type_set_nontrivial_flag): New.
(trivial_fn_p): New.
(do_build_copy_constructor): Use it.
(do_build_assign_ref): Likewise. Handle move assignment.
(build_stub_type, build_stub_object, locate_fn_flags): New.
(locate_ctor): Use locate_fn_flags.
(locate_copy, locate_dtor): Remove.
(get_dtor, get_default_ctor, get_copy_ctor, get_copy_assign): New.
(process_subob_fn, synthesized_method_walk): New.
(maybe_explain_implicit_delete): New.
(implicitly_declare_fn): Use synthesized_method_walk,
type_has_trivial_fn, and type_set_nontrivial_flag.
(defaulted_late_check): Set DECL_DELETED_FN.
(defaultable_fn_check): Handle sfk_move_assignment.
(lazily_declare_fn): Clear CLASSTYPE_LAZY_* early. Don't declare
implicitly deleted move ctor/op=.
* search.c (lookup_fnfields_1): Handle sfk_move_assignment.
(lookup_fnfields_slot): New.
* semantics.c (omp_clause_info_fndecl): Remove.
(cxx_omp_create_clause_info): Use get_default_ctor, get_copy_ctor,
get_copy_assign, trivial_fn_p.
(trait_expr_value): Adjust call to locate_ctor.
* tree.c (special_function_p): Handle sfk_move_assignment.
