From 63de067a1bcf57d66d6f68e6524f3e7fa8e5ea3d Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Fri, 4 Feb 2022 10:50:04 +0100 Subject: [PATCH] cmd: wrong printf() code in do_test_stackprot_fail() strlen() returns size_t. So we should use %zu to print it. This avoids incorrect output on 32bit systems.
