            Bug ID: 25598
           Summary: system_category().message() and
                    generic_category().message() are not thread safe
           Product: libc++
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P

The function __do_message::message() is inherited by __system_error_category
and __generic_error_category. This function converts an error code to a string
using strerror(). The strerror() function is not thread safe. See
include/system_error and src/system_error.cpp.

This bug could be fixed by replacing strerror() with the platform specific
thread safe version (usually strerror_r()).
