Subject: [PATCH v3 18/17] tests/unit/test-char: Replace g_alloca() by buffer on the stack
Date: Fri,  7 May 2021 19:19:48 +0200	[thread overview]
Message-ID: <20210507171948.2062076-1-philmd@redhat.com> (raw)
In-Reply-To: <20210507144315.1994337-1-philmd@redhat.com>

The ALLOCA(3) man-page mentions its "use is discouraged".

Directly reserve the CharBackend on the stack.
