The gcc4-compatible copy-on-write std::string does not conform to the C++11 requirements on data race avoidance in standard containers. Specifically, calling non-const member functions such as begin() and data() needs to do the "copy on write" operation and so is most definitely a modification of the object. As such, those non-const members must not be called concurrently with any other uses of the string object. libstdc++-v3/ChangeLog: PR libstdc++/21334 * doc/xml/manual/using.xml: Document that container data race avoidance rules do not apply to COW std::string. * doc/html/*: Regenerate. |
