  "message": "Fix a use after free bug in the tests.\n\nThe way the SystemTest fixture works is that it takes\na \"FooProblem\" object as a type, which contains a ceres::Problem\nand a ceres::Solver::Options object.\n\nThe Options object also contains a linear_solver_ordering which\ncontains double* which refer to memory that is allocated when\na problem object is created.\n\nSo it is important that the lifetime of the ceres::Problem object\nand the ceres::Solver::Options object be tied together. But we were\nviolating this by creating a FooProblem object on the stack, grabbing\nits Options struct and passing it to the SystemTest fixture, which\nwould then create another instance of FooProblem, grab its Problem\nobject and copy the modified options struct into it.\n\nIn the case where a user provided ordering was being used,\nthis ordering would now be referring to memory allocated by the first\nFooProblem object, which would cause Ceres\u0027s internal ApplyOrdering\nfunction to fail.\n\nThe fix is ofcourse to Problem and Options object that are born\ntogether.\n\nChange-Id: I07c377a9d5fcabbb6c7ca8aa3460206ce045ffa9\n",
