Information on known bugs, details on efforts to fix them, and

fixed bugs are all available as part of the GCC bug tracking

system, <a class="ulink" href="http://gcc.gnu.org/bugzilla" target="_top">bugzilla</a>, with the

|

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="ulink" href="http://www.open-std.org/jtc1/sc22/wg21/" target="_top">ISO C++
|
||
Committee homepage</a>, linked to on the
|
||
<a class="ulink" href="http://gcc.gnu.org/readings.html" target="_top">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="ulink" href="../ext/lwg-active.html#DR" target="_top">DR</a> status.
