    `CUDA_ERROR_ILLEGAL_ADDRESS` failures.

    A fix in CUDA 9.1.121 is expected in late February 2018. We do not expect a
    fix for CUDA 9.0.x. Until the fix is available, the only workaround is to
    [downgrade](https://developer.nvidia.com/cuda-toolkit-archive) to CUDA 8.0.x
    or disable XLA:GPU.
