HI I Have checked the crash log. the result is bellow.
If I am reading it and following the mpirun code correctly the release of the last mca_pls_xgrid_component.client by orte_pls_xgrid_finalize causes a call to method dealloc for PlsXGridClient where a [connection finalize] 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.
