<h4>Compatibility</h4>
<p>Around 99% of tests pass when compiling {@code libc++} with Clang 3.4 for all supported ABIs.
The failures are mostly in the areas of {@code wchar_t} and locales that Android bionic
doesn't support. Switching locale from the default produces the following warning in
{@code logcat}:</p>
<p>The NDK's libc++ is not stable. Not all the tests pass, and the test suite is not comprehensive.
Some known issues are:</p>
<ul>
<li>Using {@code c++_shared} on ARM can crash when an exception is thrown.</li>
<li>Support for {@code wchar_t} and the locale APIs is limited.</li>
</ul>
<p>You should also make sure to check the "Known Issues" section of the changelog for the NDK
release you are using.</p>
<p class="note"><strong>Warning: </strong>Attempting to change to an unsupported locale will
<strong>not</strong> fail. The operation will succeed, but the locale will not change and the
following message will appear in {@code logcat}.</p>
