After a little digging, I am able to run your code (it looks like it
expects both an input file and an output file on the command line, or
it segv's). But I don't get those errors, either with OMPI v1.2.8 or
the upcoming v1.3 series; I ran with as many as 16 processes across 4
Can you narrow the problem down a bit more? You still didn't provide
too many details about the problem. :-)
