The deserialize() for std::string was written under the assumption that std::string · 4bc01864

Davis King authored Apr 29, 2011

doesn't store it's data in a contiguous block.  However, that isn't quite the case.
See this discussion:
http://stackoverflow.com/questions/1986966/does-s0-point-to-contiguous-characters-in-a-stdstring

directly into the string rather than into a contiguous buffer and then do a copy.
