Paolo Carlini <paolo.carlini at oracle dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC|lundberj at gmail dot com | --- Comment #2 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-08-18 20:58:35 UTC --- Many C++11 bits having to do with iostream and even more those having to do with std::string are quite delicate in terms of ABI, thus the implementation is being delayed to when we globally break the ABI. It's known.
