[boost] boost::lock_error - documentation bug

Hi everybody, there seems to be a bug in the documentation (or implementation?) of boost::lock_error. The documentation (http://www.boost.org/doc/html/lock_error.html) describes lock_error as: Synopsis: class lock_error : public std::logical_error { ... Whereas them implementation (1.32.0, thread/exceptions.hpp) declares boost::lock_error as derived from boost::thread_exception which is derived from std::exception and nothing more. Even assuming std::logic_error was ment (there is no class std::logical_error ) I'd say that's a documentation bug. I haven't looked through all the other exception classes defined by boost::thread ... maybe someone should :-) bye, Paul
