Information on known bugs, details on efforts to fix them, and
fixed bugs are all available as part of the <a class="link" href="http://gcc.gnu.org/bugs/">GCC bug tracking system</a>,
with the category set to <code class="literal">libstdc++</code>.

Everybody's got issues. Even the C++ Standard Library.
</p><p>
The Library Working Group, or LWG, is the ISO subcommittee responsible
for making changes to the library. They periodically publish an
Issues List containing problems and possible solutions. As they reach
a consensus on proposed solutions, we often incorporate the solution.
</p><p>
Here are the issues which have resulted in code changes to the library.
The links are to the specific defect reports from a <span class="emphasis"><em>partial
copy</em></span> of the Issues List. You can read the full version online
at the <a class="link" href="http://www.open-std.org/jtc1/sc22/wg21/">ISO C++
Committee homepage</a>, linked to on the
<a class="link" href="http://gcc.gnu.org/readings.html">GCC "Readings"
page</a>. If
you spend a lot of time reading the issues, we recommend downloading
the ZIP file and reading them locally.
</p><p>
(NB: <span class="emphasis"><em>partial copy</em></span> means that not all
links within the lwg-*.html pages will work. Specifically,
links to defect reports that have not been accorded full DR
status will probably break. Rather than trying to mirror the
entire issues list on our overworked web server, we recommend
you go to the LWG homepage instead.)
</p><p>
If a DR is not listed here, we may simply not have gotten to
it yet; feel free to submit a patch. Search the include/bits
and src directories for appearances of
<code class="constant">_GLIBCXX_RESOLVE_LIB_DEFECTS</code> for examples
of style. Note that we usually do not make changes to the
code until an issue has reached <a class="link" href="../ext/lwg-active.html#DR">DR</a> status.
