We should let fibers update their own references on compaction. I don't
think we need the thread to update the associated fiber because there
will be a fiber object on the heap that knows how to update itself.
The added test case crashes the interpreter because it makes
ObjectSpace.internal_class_of return the second VALUE slot of an AST
imemo object. The second VALUE slot of `struct rb_ast_struct` is
not a VALUE and not a pointer to a Ruby object.
Since r63443, `-std=gnu99 -D_XOPEN_SOUCE=x00` is added to Solaris'
`CPPFLAGS`. `CPPFLAGS` is shared among `CC` / `CXX`. This results in
both `__STDC_VERSION__` and `__cplusplus` to be defined at the same time
for a C++ compilation, only on Solaris.
It seems the `CPPFLAGS` addition is intentional. We sould not touch
that part. Instead we need to reroute this by always check for
`__cplusplus` first.
by explicitly setting `Warning[:deprecated] = true`.
I removed "capture_io" at 79063d8cbf, but
it printed the warning when `RUBYOPT=-w`.
This change makes the warnings enabled explicitly, capture and check the
warning.
The memory view interface added at 890bc2cdde is experimental new C-API
set. This feature permits extension libraries to share a memory area
that contains such a numerical array and a bitmap image. This is
designed by referring to Python's buffer protocol.

The only remaining use of this function was to get the internal
message object from an exception's hidden `mesg` instance
variable to allow it to be dumped wiithout converting to a string.
As discussed in #103, this exposes internal implementation details
of CRuby, and ultimately does not provide any real utility to the
user since they can't directly inspect this hidden variable. The
test change here is to reflect CRuby behavior that denies equality
if the internal message objects do not match, as is the case after
the exception has been loaded and now has a simple String value.
The impact to users is that exceptions with special hidden message
objects will convert those objects to String during marshaling
through YAML. I believe this only affects NameError and its
descendants, since users can't set this field directly on their
own exception types.
Fixes#103.
