21 // A generic exception class supporting std::string error messages
22 // (unlike std::exception, which only supports const char* error
23 // messages). If execinfo is available and ENABLE_DYNAMIC_BACKTRACE
24 // is defined, it also generates information about the state of the
25 // stack at the time of its instantiation (if not, then
26 // get_backtrace() returns an empty string).
