[petsc-users] A bad commit affects MOOSE

[Kong, Fande]

Hi All,

I am trying to upgrade PETSc from 3.7.6 to 3.8.3 for MOOSE and its
applications. I have a error message for a standard test:









*preconditioners/pbp.lots_of_variables: MPI had an

I did "git bisect', and the following commit introduces this issue:

hpmat already stores two HYPRE vectors*

Before I debug line-by-line, anyone has a clue on this?
