Something broke; I think I see what it is from your logs. I'll fix it.<br><br>- Peter<br><br><div class="gmail_quote">On Mon, Aug 13, 2012 at 9:17 PM, Barry Smith <span dir="ltr"><<a href="mailto:bsmith@mcs.anl.gov" target="_blank">bsmith@mcs.anl.gov</a>></span> wrote:<br>

What's up with this stuff? Are they bugs? Bad algorithms? What? It is hard to make a major change to PETSc (and use alltests to check that you haven't broken anything) when this crap comes up constantly.<br>

Is there a plan to deal with this or are we just screwed forever?<br>
