From 6e7d0efa9058aa61147d9d18b33bd046055584e4 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 14 Mar 2011 12:29:50 -0700 Subject: list-objects.c: don't add an unparsed NULL as a pending tree "git rev-list --first-parent --boundary $commit^..$commit" segfaults on a merge commit since 8d2dfc4 (process_{tree,blob}: show objects without buffering, 2009-04-10), as it tried to dereference a commit that was discarded as UNINTERESTING without being parsed (hence lacking "tree").
