Eric,
I have now updated all the standard MPI matrix types AIJ, BAIJ, SBAIJ to
print the correct global indices in the error messages when a new nonzero
location is generated thus making debugging this issue easier. In the branches

My admin did an install of petsc on ubuntu 14.0 using the package manager.
Things seem to be ok, expect I noticed the following when I compile using the
petsc rules:
mpicxx -o ex19.o -c -Wall -Wwrite-strings -Wno-strict-aliasing
-Wno-unknown-pragmas -O -fPIC

Klaus,
You would really benefit by upgrading to PETSc 3.5.3, we added much faster
symbolic MatAXPY() for the DIFFERENT_NONZERO_STRUCTURE flag. Plus it is much
easier for us to support the newest version.
