Key: STDCXX-1016
URL: https://issues.apache.org/jira/browse/STDCXX-1016
Project: C++ Standard Library
Issue Type: Improvement
Components: 22. Localization

Environment: All
Reporter: Farid Zaripov
Assignee: Farid Zaripov
Priority: Trivial

Currently the _C_mutex data member of the __rw::__rw_locale class is mentioned
only in _C_add_ref () and _C_remove_ref () methods of this class. But neither
_C_add_ref () nor _C_remove_ref () are not invoked from anywhere.
