Bug#623876: libc6: valgrind has many issues with libc6

[Brian Paterni <bpaterni@gmail.com>]

Package: libc6
Version: 2.13-0exp5

If I run virtually any program through with valgind, I'm pretty much guaranteed
to get at least a few errors/warnings caused by libc6. Even running a simple
program like:

int main(int argc, char **argv)
{
	return 0;
}

produces a couple valgrind warnings:
