Just to put an end-cap on this.... I switched over to the newest

That's a relief! Thanks for keeping us updated!
It'd be nice to know what caused the issue, but probably not worth the
massive effort it'd take to debug.
I generally like how we add workarounds for compile-time problems with
old PETSc versions and compiler versions, because that's generally
easy enough to do... but for run-time problems with old MPI versions,
forget about it. I've also got a "breaks-with-old-mpich2,
works-with-new" bug on my plate here that I'm never planning to really
investigate.
