From d8f8a126658a25fdad5e9fb00b1b0838a7e93c68 Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Fri, 8 Aug 2008 22:18:00 -0500 Subject: Fix segfault on x86_64 when using UseSyslog Due to differences in handling va_list between i686 and x86_64, this bug can only be seen on x86_64. va_list usage is not allowed but we had been getting away with it. See http://lists.opensuse.org/opensuse-programming/2008-02/msg00005.html for details and explanation. This fixes FS#11096.
