Subject: [OMPI devel] Open MPI's 'mpiexec' trash output of program being aborted?
From: Paul Kapinos (kapinos_at_[hidden])

Dear Open MPI developer,

Please take a look at the attached 'program'.

In this program, we try to catch signals send from outside, and "handle" them.
In case of different signals different output has to be produced.

When you start this file directly, or using 'mpiexec' from Intel MPI, and then
abort it by Ctrl-C, the output "SIGINT received" is written to file and to StdOut.

When you start this file using Open MPI's 'mpiexec', the output is written to
file, but *not* to StdOutput - 'mpiexec' seem to nick it.

Is that behaviour intentionally? (it is quite uncomfortable, huh)
