While in the process of tracking another bug (possibly not in libcurl), I ran into a problem with disabling the DNS cache on Windows XP (using CURLOPT_DNS_CACHE_TIMEOUT).
 
I had introduced into a Java servlet a loop that would cause the TIMEOUT on libcurl would be hit. This seems to work fine, but the very next request (using the same curl handle) cause an exception in Curl_connecthost, line 604:
 
     if(!remotehost->addr->h_addr_list[0]) {
 
It seems that 'remotehost->addr' is null.
 
As soon as I turn DNS cache back on, it works fine.
 
Also, previously we were using 7.10.1-1, and did not experience this problem.
 
One more also... If I force a delay (say 45-60 seconds) after the timeout (before doing the next request), it seems to work fine.
