  "message": "Fix Eigen3 Row/Column Major storage issue.\n\nEigen3 does not allow column vectors to be stored in row-major\nformat. NumericDiffCostFunction by default stores its Jacobian\nmatrices in row-major format. This works fine if the residual\ncontains more than one variable. But if the residual block\ndepends on one variable and has more than one residuals, the\nresulting Jacobian matrix is a column matrix in row-major format\nresulting in a compile time error.\n\nThe fix is to check the template parameters and switch to column-major\nstorage as needed.\n\nThanks to Lena Gieseke for reporting this.\n\nChange-Id: Icc51c5b38e1f3609e0e1ecb3c4e4a02aecd72c3b\n",
