<div>
<pre>When testing libc++ with MSAN tests involving wide strings start to fail
without MSAN producing any output. The assertions in these tests do not fail
when MSAN is disabled.
The output of the test run can be found here:
<a href="http://lab.llvm.org:8011/builders/libcxx-libcxxabi-x86_64-linux-ubuntu-msan/builds/9/steps/test.libcxx/logs/stdio">http://lab.llvm.org:8011/builders/libcxx-libcxxabi-x86_64-linux-ubuntu-msan/builds/9/steps/test.libcxx/logs/stdio</a>
libc++ is compiled with the sanitizer flags:
-fno-omit-frame-pointer -fsanitize=memory
Let me know if I can provide anything more.</pre>
