Yes, this commit was buggy, but somehow when we merged the PIPECG implementation, it didn't come with any tests, so we didn't notice. I'll fix it after my meeting this morning and we'll get it into the upcoming petsc-3.5.3. https://bitbucket.org/petsc/petsc/commits/04d66c6e00809e52f621f72696de30b33e3deda5
