Further to this - do I recall someone saying they had unpushed bug fixes
to the test cases? For example, I've tried:

ggorman at cynic:~/projects/petsc/petsc-dev/src/ksp/ksp/examples/tests$
./ex10 -m 4
m = 2, N=375

--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 63.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
--------------------------------------------------------------------------

Pretty much the only value for the problem size (ie the -m option) is
the default.
