Hi David,

Confirmed as fixed here.

Core was generated by `/tmp/tmpti8F3zexe'.

It's not obvious to me how this particular failure is specific to libcxxrt.  One thing that I do find a little strange is that libcxxrt links to libstdc++.so.6, so perhaps we're seeing a symbol conflict?  That, however, is probably off-topic for this list :-)
