+Subject: [PATCH] src/libmowgli/dns/evloop_res.c: fix memory leak
+
+mowgli_dns_evloop_init() [called by mowgli_dns_create()] allocates
+a random number generator and assigns it to `dns->state->rand', but
+mowgli_dns_evloop_destroy() [called by mowgli_dns_destroy()] does
+not free this object.
+
+This was found while running Atheme IRC Services (atheme/#621) under
+Valgrind.
