That's really interesting. THis is on a Leopard system, right? I'm the author/maintainer of the xgrid code. Unfortunately, I've been hiding trying to finish my dissertation the last couple of months. I can't offer much advice without digging into it in more detail than I have time to do in the near future.

I Have checked the crash log.
the result is bellow.
If I am reading it and following the mpirun code correctly the release of

is call that ends as a [NSObject finalize]
I think is as intended, anyone knows if that is correct?
but for some unknown reason is not liked for my configuration.
The only thing that I can find is that the behaviour of the finalize
method in NSObject depends of the status of garbage collection.
I am using gcc-4.4 and Xcode 3.1.2.
