Hi!

There appears to be a bug in the openssl program which has persisted for 
years (as it appears from the Google search results).

I'm using s_server as follows

openssl s_server -accept 8888 -cert issuer.pem -key issuer.key

If the incoming connection is from localhost --

Using default temp DH parameters
Using default temp ECDH parameters
ACCEPT
gethostbyname failure
    0 items in the session cache
    0 client connects (SSL_connect())
    0 client renegotiates (SSL_connect())
    0 client connects that finished
    0 server accepts (SSL_accept())
    0 server renegotiates (SSL_accept())
    0 server accepts that finished
    0 session cache hits
    0 session cache misses
    0 session cache timeouts
    0 callback cache hits
    0 cache full overflows (128 allowed)

I dont understand why it runs gethostbyname on the incoming address in 
the 1st place.
