Is this the issue you are trying to debug and reproduce? This build is with clang/clang++

petsc at petsc:~$ clang --version
clang version 3.6.0 (tags/RELEASE_360/final)
Target: x86_64-unknown-linux-gnu
Thread model: posix

Looking at the logfile - the message says:

>>>>>>>>
/sandbox/petsc/petsc.clone-2/include/petscsys.h:2534:29: note: candidate function not viable: no known conversion from 'PetscInt *' (aka 'long *') to 'PetscMPIInt *' (aka 'int *') for 7th argument
<<<<<<<

So perhaps the following fix? [the compile goes through for me with this change. The other warninings still reamin]
