  "message": "Make canned loss functions more robust.\n\nThe loss functions that ship with ceres can sometimes\ngenerate a zero first derivative if the residual is too\nlarge.\n\nIn such cases Corrector fails with an ugly undebuggable\ncrash. This CL is the first in a series of fixes to\ntake care of this.\n\nWe clamp the values of rho\u0027 from below by\nnumeric_limits\u003cdouble\u003e::min().\n\nAlso included here is some minor cleanup where the constants\nare treated as doubles rather than integers.\n\nThanks to Pierre Moulon for reporting this problem.\n\nChange-Id: I3aaf375303ecc2659bbf6fb56a812e7dc3a41106\n",
