From d551bbaf3af1fad947c704bdeb9cf664b34e38c6 Mon Sep 17 00:00:00 2001 From: Thomas Rast Date: Sat, 6 Dec 2008 21:50:09 +0100 Subject: [PATCH] fetch-pack: Avoid memcpy() with src==dst memcpy() may only be used for disjoint memory areas, but when invoked from cmd_fetch_pack(), we have my_args == &args. (The argument cannot be removed entirely because transport.c invokes with its own variable.)
