Subject: Re: [OMPI devel] valgrind warnings (uninited mem passed to syscall)

There is not at this point. There's stuff in the works (HLRS is
working on some cool valgrind integration which goes beyond normal
memory checking), but it's not ready yet.

I'm aware of at least one place in the oob tcp that gets such a
warning (we're sending an entire struct down the wire, but there's
some "holes" in the memory such that we don't care about the values
and they are therefore uninitialized); where are you seeing the issue?
