The problem with both the f77 and f90 programs is that you forgot to
put "ierr" as the last argument to MPI_PACK. This causes a segv
because neither of them are correct MPI programs.
But it's always good to hear that we can deliver a smaller corefile
in v1.2! :-)

I have a small program in F77 that makes a SEGV crash with
a 130MB core file. It is true that the crash is much cleaner
in OpenMPI 1.2; nice improvement! The core file is 500 MB with
OpenMPI 1.1.
I am running on CentOS 4.4 with the latest patches.
