We are having some problems with master and MPICH 1 in the nightly tests
http://ftp.mcs.anl.gov/pub/petsc/nightlylogs/archive/2015/06/08/examples_master_arch-linux-mpich1_steamroller.log 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. Barry
