This is probably the lowest priority of our build failures. But if this failure indicates another buried issue which has wider impact, let's dig into it. d1c2ae72c482 OS X 10.8 C++11 DEBUG core (logfile)
The output is really brief:
What's interesting is that it has been failing consistently since d2651c8f82d9 (CommitDate: Wed Oct 2) d2651c8f82d9 OS X 10.8 C++11 DEBUG core And it was solid green before that. |

Bumping to 2.5.4: We don't need 2.5.3 green on C++11 builders, and we do understand the root cause. I do have a fix ready, but not worth even the low risk of disrupting 2.5.3 to get this in this late in the game. |

I'd hoped to be able to patch this in a way that would never require that we revisit it, but apparently we can't test the __clang_major__ and __clang_minor__ defines meaningfully due to Apple's meddling (see http://stackoverflow.com/questions/19387043/how-can-i-reliably-detect-the-version-of-clang-at-preprocessing-time). We will need to make the test unconditional to skip the test on clang, at least until we know that all platforms we want to target are clang-3.3 or better. |

This is a known issue, tracked in As for why it went from solid green to solid red: we turned on optimization for all DEBUG builds, so the cause of this is is in the MCI configuration repo, not the mongodb repo. As potential short term workarounds, we can either turn optimization off for this builder (assuming it doesn't run any tests that will take an egregiously long time in that mode - we can look and see what the total test runtime for the builder was for some build before we enabled optimizations), or we can just #ifdef out this particular test when _clang_ is defined, until we can move to XCode 5. |
