I'd be embarrassed to admit how many times I make the same mistake. And I've been working on Open MPI for over 10 years. :-)

> With regards to openmpi-1.6.5, the system that I'm compiling and running on, SLES10, contains some pretty dated software (e.g. Linux 2.6.x, python 2.4, gcc 4.1.2). Is it possible there's simply an incompatibility lurking in there somewhere that would trip openmpi-1.6.5 but not openmpi-1.4.3?

Possibly, but I'd be a bit surprised if that were the case.

So are we back to the state of: stuck in MPI_Finalize in 1.6.x for hello_c.c?
