  "message": "Use default alignment if alignof(std::max_align_t) \u003c 16 with C++11.\n\n- As per Andrew Hunter’s comments in the commit which added Jet\n  alignment when using C++11 here:\n  https://ceres-solver-review.googlesource.com/#/c/7100, there is wide\n  lattitude in the standard about what the maximum supported alignment\n  can be.\n- Previously, we were forcing the alignment to 1, if the value of\n  alignof(std::max_align_t), which we use as a proxy for the maximum\n  supported alignment on the platform, was \u003c 16.\n- An alignment of 1 is not valid for Jets, as it would weaken the\n  natural alignment of the types within a Jet, which would typically be\n  4 (32-bit systems) or 8 (64-bit systems), thus resulting in a compiler\n  error.\n- This was reported as issue 235 for Clang 3.8 on i386:\n  https://github.com/ceres-solver/ceres-solver/issues/235.\n\nChange-Id: Ie39e5499c64f9231f29ebf4392992b5c9ce2e385\n",
