From 9be951a41503cd212d035496a003924f00b7aa06 Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Thu, 1 Jul 2010 23:32:20 +0200 Subject: multi: CURLINFO_LASTSOCKET doesn't work after remove_handle When curl_multi_remove_handle() is called and an easy handle is returned to the connection cache held in the multi handle, then we cannot allow CURLINFO_LASTSOCKET to extract it since that will more or less encourage that the user uses the socket while it can get used by libcurl again. Without this fix, we'd get a segfault in Curl_getconnectinfo() trying to dereference the NULL pointer in 'data->state.connc'.
