Subject: [Outreachy] [PATCH v2] bisect--helper: avoid free-after-use
Date: Mon, 9 Dec 2019 11:56:47 +0100 [thread overview]
Message-ID: <20191209105647.21855-1-mirucam@gmail.com> (raw)
From: Tanushree Tumane <tanushreetumane@gmail.com>
In 5e82c3dd22a (bisect--helper: `bisect_reset` shell function in C,
2019-01-02), the `git bisect reset` subcommand was ported to C. When the
call to `git checkout` failed, an error message was reported to the
user.
However, this error message used the `strbuf` that had just been
released already. Let's switch that around: first use it, then release
it.
