Subject: [dpdk-stable] [PATCH v10 4/4] performance-thread: Fix cross compilation failed
Date: Fri, 15 Oct 2021 23:11:10 +0800
Message-ID: <20211015151110.1876850-4-zhihongx.peng@intel.com> (raw)
In-Reply-To: <20211015151110.1876850-1-zhihongx.peng@intel.com>

From: Zhihong Peng <zhihongx.peng@intel.com>

The gcc(arm-linux-gcc) will check code more stricter when ASan enabled.
"strncpy specified bound XX equals destination size" error occurs here.

Fixes: 116819b9ed0d ("examples/performance-thread: add lthread subsystem")
Cc: stable@dpdk.org
