Re: [patch] file descriptor leak fix

The leak reported by Igor is in opentemp(). The only place opentemp() is called from is diffreg(). When diffreg() is called from main(), the only calls that follow are print_status() and exit(), so we do not really leak anything: opentemp() leaks ifd, returns NULL, diffreg() returns, main()
