Basically, make an object graph of all of living objects before and
after marking and check status.
[Before marking: check WB sanity]
If there is a non-old object `obj' pointed from old object
(`parent') then `parent' or `obj' should be remembered.
[After marking: check marking miss]
Traversible objects with the object graph should be marked.
(However, this alert about objects pointed by machine context
can be false positive. We only display alert.)
[Implementation memo]
objspace_allrefs() creates an object graph.
The object graph is represented by st_table, key is object (VALUE)
and value is referring objects. Referring objects are stored by
"struct reflist".
* gc.c (init_mark_stack): do not use push_mark_stack_chunk() at init.
This pre-allocation causes failure on is_mark_stask_empty()
without any pushing.

hash defininition because SystemStackError raises at line 3 on
FreeBSD, for unknown reason.

when full_mark is 0.
rb_gc_mark_symbols() (with full_mark == 1) can be called by other
than GC (such as rb_objspace_reachable_objects_from_root()).

* Remove Rubinius exception since transcoding should be working now.
* Fix https://github.com/flori/json/issues/162 reported by Marc-Andre
Lafortune <github_rocks@marc-andre.ca>. Thanks!
* Applied patches by Yui NARUSE <naruse@airemix.jp> to suppress
warning with -Wchar-subscripts and better validate UTF-8 strings.
* Applied patch by ginriki@github to remove unnecessary if.
* Add load/dump interface to JSON::GenericObject to make
serialize :some_attribute, JSON::GenericObject
work in Rails active models for convenient
SomeModel#some_attribute.foo.bar access to serialised JSON data.

* eval_jump.c (rb_exec_end_proc): reduce number of pushing/popping
and reuse same tag.

NoMethodError when the original of alias is not found.

that super calls proper method.

OS version string.

no sense on platforms where link count is not provided.

* lib/rubygems/util.rb (Gem::Util.popen): should close open pipe to
reap the child process, in 1.9 or later. fix deadlock on waiting
the child process whose output is bigger than pipe buffer, in 1.8.

rb_fstring() used rb_gc_mark() to avoid freeing used string.
However, rb_gc_mark() set mark bit *and* pushes mark_stack.
rb_gc_resurrect() does only set mark bit if it is before sweeping.
* string.c (rb_fstring): use rb_gc_resurrect.
* internal.h: add decl.

Improved accessibility of the main sidebar navigation.
Fixed handling of regexp options in HTML source highlighting.
* test/rdoc: ditto.

Compatibly renamed Gem::DependencyResolver to Gem::Resolver.
Added support for git gems in gem.deps.rb and Gemfile.
Fixed resolver bugs.
* test/rubygems: ditto.
* lib/rubygems/LICENSE.txt: Updated to license from RubyGems trunk.
[ruby-trunk - Bug #9086]
* lib/rubygems/commands/which_command.rb: RubyGems now indicates
failure when any file is missing. [ruby-trunk - Bug #9004]
* lib/rubygems/ext/builder: Extensions are now installed into the
extension install directory and the first directory in the require
path from the gem. This allows backwards compatibility with msgpack
and other gems that calculate full require paths.

* eval_intern.h (TH_PUSH_TAG, TH_EXEC_TAG): refine stack overflow
detection. chain local tag after setjmp() successed on it, because
calling setjmp() also can overflow the stack.

TH_EXEC_TAG().
