Subject: [Tarantool-patches] [PATCH 2/3] lua/errno: shrink memory usage on error declaration
Date: Thu, 17 Sep 2020 16:51:20 +0300	[thread overview]
Message-ID: <20200917135121.60380-3-gorcunov@gmail.com> (raw)
In-Reply-To: <20200917135121.60380-1-gorcunov@gmail.com>

There is no need to allocate 32 bytes per each string,
the backend lua does copy the string internally thus
plain pointer is enough here no need to allocate redundant
memory.

Part-of #5034
