std::map<type_info_, shared_ptr<error_info_base> > in error_info_container_impl. This map is copied in clone(). However, type_info_ contains a member which is a reference, so it is not copyable.

The standard says that you can only copy a std::map<T,U> if both T and U are copyable. Some standard libraries don't make use of this requirement, but libc++ does.

The easiest fix to this would be to make type_info_ take it's reference member instead by pointer, and make it copyable.

Before I prepare a full patch, I wondered if anyone had any comments, as this is a fairly big change to boost::exception",Bugs,closed,To Be Determined,exception,Boost Development Trunk,Problem,fixed,,
