From ed79f37d9b6f1d3543afe5103bbe9dab43484b66 Mon Sep 17 00:00:00 2001 From: Zhou Jie Date: Fri, 29 Apr 2016 13:12:01 +0800 Subject: block: always compile-check debug prints Files with conditional debug statements should ensure that the printf is always compiled. This prevents bitrot of the format string of the debug statement. And switch debug output to stderr.
