I saw some test results, and they are the failures I also sometimes see: the skeleton&contents tests sometimes fail, and sometimes work. This is the same as in the past and Doug Gregor had explained it as a problem of the underlying MPI implementation. Looking deeper into it would require more time than is available. These are not regressions but issues that have been around for a while.
Thanks, Matthias. This is good enough for me to feel comfortable moving ahead with the 1.40 release. Beman, Jeremiah, any objections? -- Eric Niebler BoostPro Computing http://www.boostpro.com

Are there any concerns with the Intel problems I posted about? Does MPL's static assert mechanism have any problems on that platform? If I can run the tests on GCC 4.3 on Linux here, I think I can accept intermittent failures on that same platform on another machine. What MPI is Steve using, and what version? -- Jeremiah Willcock

I'm not ignoring that failure, but I don't think it is a showstopper. If it's broken with Intel 10 on Linux, I think that's something we can live with for 1.40 and fix for 1.41. I'm satisfied knowing that MPI is not fundamentally broken across the board. The failure you mention certainly bears investigation, though. Could you open a bug report against MPI? If it turns out to be a MPL issue, we can reassign it. Thanks, -- Eric Niebler BoostPro Computing http://www.boostpro.com

I am able to reproduce the skeleton&content errors fairly consistently now, but I don't understand the mechanism enough to debug it. If you use "-mca btl tcp,self" on the mpirun command line (running the test by hand), the memory errors turn into test failures, at least for me. I think I need Matthias to help with debugging the problems. -- Jeremiah Willcock

Makes sense to me. I've got a couple of private emails asking for merges. I'm about to review them and will then post updated plans. --Beman
