> traffic_server - STACK TRACE:
> {code}
> seems to crash at the line if (!m_log->m_start_time) and from the
> constructor looks like it will be NULL for the pipes:
> {code}
> if (m_file_format != LOG_FILE_PIPE) {
> m_log = new BaseLogFile(name, m_signature);
> m_log->set_hostname(Machine::instance()->hostname);
> } else {
> m_log = NULL;
> }
> {code}
> im still unsure how this wasn in a problem in 5.3.x, but im seeing this only
> in the newest code
