- Use atexit to register a dbg cleanup function that closes the logfile. LeakSantizier (LSAN) calls _exit() instead of exit() when a leak is detected on exit so the logfile must be closed explicitly or data could be lost. Though _exit() does not call atexit handlers such as this, LSAN's call to _exit() comes after the atexit handlers are called. Prior to this change the logfile was not explicitly closed so it was possible that if LSAN detected a leak and called _exit (which does not flush or close files like exit) then the logfile could be missing data. That could then cause curl's memanalyze to report false leaks (eg a malloc was recorded to the logfile but the corresponding free was discarded from the buffer instead of written to the logfile, then memanalyze reports that as a leak).
