[sr-dev] [kamailio] http_query causes memory corruption with AVPs (#212)

I have found an instance where using an avp or xavp as the response variable for http_query will cause a segfault later in t_relay().  When I change the variable to a $var instead of an avp, there is no segfault.

I can only recreate it with a specific URL. If I try to reproduce it by simply sending a plain text response from a static page, it does not segfault.
The http_query command is as follows:
http_query("http://cnam.dashcs.com/?companyId=XXXXX&password=XXXXXXX&number=$avp(from_phone)", "$avp(cnam)");
