From 2738bc3f09fa1baa3e664a6389394ca51e4fd376 Mon Sep 17 00:00:00 2001 From: Tay Ray Chuan Date: Wed, 31 Aug 2011 12:48:46 +0800 Subject: xdiff/xprepare: initialise xdlclassifier_t cf in xdl_prepare_env() Ensure that the xdl_free_classifier() call on xdlclassifier_t cf is safe even if xdl_init_classifier() isn't called. This may occur in the case where diff is run with --histogram and a call to, say, xdl_prepare_ctx() fails.
