I have merged the fix to stable/10 in r261644, and while I was at it, I
sync'd up stable/9 too, in r261645.  There are now only two differences
left between the version of libcxxrt in head and in stable/{9,10}; one
of these will be MFC'd very soon, and the other is up for reversal.

It is easy to cherry-pick.  Either use svn to merge changelist 260553 to
your local source tree, or download the following as a patch, and apply
it manually:

http://svnweb.freebsd.org/base/head/lib/libcxxrt/Version.map?view=patch&r1=260553&r2=260552&pathrev=260553

Then do:

cd /usr/src/lib/libcxxrt
make
sudo make install

Unfortunately, we only patch releases for security issues.  So the
earliest will either be 10.1-RELEASE or 9.3-RELEASE, since 8.x has
neither clang nor libcxxrt.

That said, 10-STABLE should mostly be just fine to run on a daily basis.
