From 7dbf66713f22b5e04a36d300307a4df7e375e76b Mon Sep 17 00:00:00 2001 From: Nick Mathewson Date: Thu, 19 Sep 2013 12:22:49 -0400 Subject: When freeing a cert_list_t, avoid memory leak. We were freeing these on exit, but when we added the dl_status_map field to them in fddb814f, we forgot to arrange for it to be freed. I've moved the cert_list_free() code into its own function, and added an appropriate dsmap_free() call.
