* ext/objspace/objspace.c (reachable_object_from_root_i):

2013-12-15T04:42:23+00:00

  reachable objects should not include categories and
  category_objects because it is noisy information.
  In fact, objects created after calling
  ObjectSpace.reachable_objects_from_root should not be included
  as a returning hash objects. Currently, mswin64 platform has a
  problem because of this behaviour. Should we trace new objects?

  is frozen.
  rb_class_path() can modify frozen classes (and causes errors).
  This patch is temporary. We need no-modification/no-allocation
  class path function.
