Let's make sure error messages have been enabled in your build.  What
configure options did you use when building mpich2?

This looks like something might be getting corrupted in the stack.  Can
you try running your application with valgrind?  E.g.,:

    mpiexec -n 5 valgrind -q ./myapp

The output of all of the processes will be interleaved, but you should
be able to see if an error is generated somewhere.
