Subject: [PATCH 11/20] mmapped_ref_iterator_advance(): no peeled value for broken refs
Date: Wed, 13 Sep 2017 19:16:05 +0200	[thread overview]
Message-ID: <d34d2cbde67e9ef0b0b11910de19c7f722c2314c.1505319366.git.mhagger@alum.mit.edu> (raw)
In-Reply-To: <cover.1505319366.git.mhagger@alum.mit.edu>

If a reference is broken, suppress its peeled value.
