  "message": "Fix a bug in DynamicAutoDiffCostFunction\n\nDynamicAutoDiffCostFunction::Evaluate when provided with a jacobians\narray that was non-empty but all its entries are nullptr, would\ncompute num_active_parameters \u003d 0, and then skip over all the loops\nthat evaluated the CostFunctor.\n\nThe fix is to check if num_active_parameters \u003d\u003d 0, and then treat\nit as the case where jacobians array is null.\n\nThanks to Ky Waegel for reporting and providing a reproduction for this.\n\nChange-Id: Ib86930c2c3f722724d249f662bf88238679bbf98\n",
