Subject: Re: [OMPI devel] Suspicious warnings from gcc-4.5.0 (both 1.4.3rc1 and 1.5rc5)

Hi Paul

Much appreciate all your testing!

Quick question here: is this on compile, or were you trying to run something?

We haven't seen this before, but I'm wondering if it is due to us failing to initialize an object's fields. If so, then it might be we don't see it because those fields usually default to zero (looks like NULL), but you might see it if they don't on your system.
