Interesting, thanks for the report!  Could you add '-g' to CFLAGS to get
more useful valgrind output (e.g., line numbers)?  Also, does this
happen when you don't pass the optimization parameters?

I have a corei7, but my gcc (from Debian squeeze) doesn't seem to like
your parameters so I couldn't try it myself.
