From cb8da70547af5cd5c8e03be5a236971951e81277 Mon Sep 17 00:00:00 2001 From: Clemens Buchacher Date: Mon, 13 Feb 2012 21:17:11 +0100 Subject: [PATCH] git rev-list: fix invalid typecast git rev-list passes rev_list_info, not rev_list objects. Without this fix, rev-list enables or disables the --verify-objects option depending on a read from an undefined memory location.
