From 2bf4263800f4ee14e2e4cd4015b2b6c46c25c845 Mon Sep 17 00:00:00 2001 From: Taylor Yu Date: Wed, 10 May 2017 13:57:18 -0400 Subject: [PATCH] Resurrect dead code in test_channelpadding.c A for-loop in test_channelpadding_timers() would never run because it was trying to increment a counter up to CHANNELS_TO_TEST/3 after an earlier block already incremented it to CHANNELS_TO_TEST/2.
