Bug 106800

stunnel-3.22-5.7.3 and later die silently in when invoked in daemon mode (with
the '-d' option).

run the following:
stunnel -D 7 -d 23 -o stunnell.log -l /usr/sbin/in.telnetd
stunnel -D 7 -c -d 446 -o stunnelr.log -r localhost:23

no stunnel processes will be seen in the output of `ps` afterward, and no errors
are sent to stdout/stderr.  `telnet localhost 446 will return "Connection
refused", I expect to a login prompt (and do on other arch-release combinations). 


here's the logs generateed from the above stunnel commands:
