My program generates the following error which I do not understand:

Is it possible I'm over running the OpenMPI buffers, my test program
works fine other than the "GPR data corruption" errors (uses
MPI_SPAWN and posted previously); the basic MPI difference between my
test program and the real program is massive amount of data being
distributed via BCAST and SEND/RECV.
It worries me that the call stack only goes that deep - there should
be more functions listed there (if nothing else, the main()
function). Can you run your application in a debugger and try to get
a full stack trace? Typically, segmentation faults point to
overwriting user buffers, but without more detail, it's hard to pin-
point the issue.
Thanks,
Brian
