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
nodes.
Can you narrow the problem down a bit more? You still didn't provide
too many details about the problem. :-)

I can't seem to run your code, either. Can you provide a more

that Rob's old post is the answer, but I can't tell from your

-- there just aren't enough details.
When I execute this code with more than once process (-n > 1), this
error message appear. My code is a distributed compressor, that the
compress task is distributed. A single process reads a block from a
file, compress it and writes a compressed block to a file.

Perhaps this post in the Open-MPI archives can help:

I already saw this post before, but this didn't help me. I'm not using
MPI_File_delete in my code.
