  "message": "Do not create a SparseCholesky object when not needed.\n\nSchurComplementSolver implements a variant of ITERATIVE_SCHUR\nwhen explicit_schur_complement is set to true. In this case\nthe SparseCholesky object should not be instantiated. Even\nthough there is no CPU cost, it can be the case that ITERATIVE_SCHUR\nis being used when there are not sparse linear algebra libraries\nare available, and this can result in a crash.\n\nChange-Id: I349d5f79201782689b3ab0ccc2c5001804b44c7b\n",
