Jed, I see the test build stops on encountering errors. This is fine for library build - but for tests - I think its best if it skips this test and continues with the remaining tests. Is this possible? http://ftp.mcs.anl.gov/pub/petsc/nightlylogs/archive/2017/01/27/examples_next_arch-linux-pkgs-valgrind_el6.log Satish
