[llvm-dev] clang-ppc64be-linux-lnt flakiness
I threw all the sanitizers I had access to on this test and didn't find anything. The merging uses threads so I can't rule out nondeterminism. It's strange that it only happens on ppc64le and only on stage 2, so an actual miscompile wouldn't surprise me either.

Thanks for taking a look. The flaky ASan test failure in the OP was stage1 so it sounds like there may be multiple problems :( -- Sean Silva On Sun, Jun 12, 2016 at 7:32 AM, Benjamin Kramer <benny.kra at gmail.com> wrote:> I threw all the sanitizers I had access to on this test and didn't > find anything.

This just failed again: http://lab.llvm.org:8011/builders/clang-ppc64le-linux-multistage/builds/1579 Bill, could you take a look at this? This is like the 3rd time I've been incorrectly pinged by this buildbot due to this issue. -- Sean Silva On Mon, Jun 13, 2016 at 8:07 PM, Sean Silva <chisophugis at gmail.com> wrote:> Thanks for taking a look.
