From 0e71bc300432b9e63bdbc8e28b0c5c0fafb601fc Mon Sep 17 00:00:00 2001 From: Thomas Rast Date: Thu, 10 Jun 2010 20:43:51 +0200 Subject: [PATCH] check_aliased_update: strcpy() instead of strcat() to copy MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit da3efdb (receive-pack: detect aliased updates which can occur with symrefs, 2010-04-19) introduced two strcat() into uninitialized strings. The intent was clearly make a copy of the static buffer used by find_unique_abbrev(), so use strcpy() instead.
