Description Sandipan Roy 2023-06-14 04:51:21 UTC 
The exact cause of this issue is the function httpClose(con->http) being called in scheduler/client.c before |httpClose(con->http); cupsdLogClient(con, CUPSDLOGWARN, "IP lookup failed - connection from %s closed!", httpGetHostname(con->http, NULL, 0));|

The problem is that httpClose always, provided its argument is not null,frees the pointer at the end of the call, only for cupsdLogClient to 
pass the pointer to httpGetHostname.
