--- Comment #4 from Yucheng Low <ylow at graphlab dot com> --- I have tried version scripts and it ought to work but I couldn't quite figure out what symbols to hide. In any case, the proposed modification does fix a questionable bit of code in locale.cc (i.e. the resize code path in _M_install_facet is problematic due to the deletion of a placement new). The effect that it resolves a compatibility issue is a pleasant side effect.
