From 4675a56a3ce2bef715386e45036426c8a4329d39 Mon Sep 17 00:00:00 2001 From: Vitezslav Cizek Date: Thu, 24 Nov 2016 13:21:41 +0100 Subject: [PATCH] apps/speed.c: Fix crash when config loading fails Move rsa_key initialization in front of load_config(). If loading the config fails, rsa_key isn't initialized and may cause invalid free() in the end: cleanup. Remove superfluous memset.
