(Fconcord_decode_object): Do GCPRO for Fconcord_make_object.

(func_for_each_object): Likewise; do GCPRO for
for_each_object_closure->function.
(Fconcord_foreach_object_in_feature): Use GCPRO4 for
for_each_object_closure->function, for_each_object_closure->genre,
for_each_object_closure->ds and for_each_object_closure->ret.
(concord_object_validate): Do GCPRO for Fconcord_make_object.
