From 1442171bc913a9cddae5c6ad0d0a4be3a1ca86e8 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Thu, 23 Oct 2008 04:32:23 +0000 Subject: [PATCH] fix overlapping memcpy in normalize_absolute_path The comments for normalize_absolute_path explicitly claim that the source and destination buffers may be the same (though they may not otherwise overlap). Thus the call to memcpy may involve copying overlapping data, and memmove should be used instead. This fixes a valgrind error in t1504.
