I cleaned up the freebsd diffs, added some magic from this thread, and filed a debbug about it (702729). I'm not 100% confident it won't cause some debian/linux regression or that it's complete, but it's a step in the right direction, particularly as it builds off of the version of valgrind presently in unstable instead of an older version such as 3.5. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=702729 Jeff
