Subject: [PATCH 3/3] bisect: fix memory leak when returning best element
Date: Wed, 1 Nov 2017 21:34:39 +0100 [thread overview]
Message-ID: <2ef8b41ad021638acc767c59ee65e15109a34fbf.1509557518.git.martin.agren@gmail.com> (raw)
In-Reply-To: <4795556016c25e4a78241362547c5468877f808d.1509557518.git.martin.agren@gmail.com>
When `find_bisection()` returns a single list entry, it leaks the other
entries. Move the to-be-returned item to the front and free the
remainder.
