[petsc-dev] problems with master and MPICH version 1

[Barry Smith]

  We are having some problems with master and MPICH 1 in the nightly tests

I've done a lot of debugging including with valgrind and cannot determine the problem. I'm concluding that it is a problem with how they handle attributes since changing the number of attributes can produce crashes or prevent crashes. It is flaky, like memory corruption problems but valgrind is happy.
