From 426193c025eb76125a99b3fe143eea50e849f9ca Mon Sep 17 00:00:00 2001 From: Erik Faye-Lund Date: Mon, 23 Mar 2009 12:53:08 +0000 Subject: [PATCH] builtin-fast-export.c: fix crash on tagged trees If a tag object points to a tree (or another unhandled type), the commit- pointer is left uninitialized and later dereferenced. This patch adds a default case to the switch that issues a warning and skips the object.
