use more than 4GB of temp memory. This results in garbage results and/or
    `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.

In short, if you had dependencies that looked like:

```Python
def my_dep():
    try:
        yield
    except SomeException:
        pass
```

Now you need to make sure you raise again after `except`, just as you would in regular Python:

expected := &Nat{[]uint{0}} if x.Equal(expected) != 1 { t.Errorf("%+v != %+v", x, expected) } x.Add(y, m) expected = &Nat{[]uint{7}} if x.Equal(expected) != 1 { t.Errorf("%+v != %+v", x, expected) } } func TestExp(t *testing.T) { m := modulusFromBytes([]byte{13}) x := &Nat{[]uint{3}} out := &Nat{[]uint{0}} out.Exp(x, []byte{12}, m) expected := &Nat{[]uint{1}} if out.Equal(expected) != 1 { t.Errorf("%+v != %+v", out, expected) } } func TestExpShort(t *testing.T) { m := modulusFromBytes([]byte{13}) x...

expected := &Nat{[]uint{0}} if x.Equal(expected) != 1 { t.Errorf("%+v != %+v", x, expected) } x.Add(y, m) expected = &Nat{[]uint{7}} if x.Equal(expected) != 1 { t.Errorf("%+v != %+v", x, expected) } } func TestExp(t *testing.T) { m := modulusFromBytes([]byte{13}) x := &Nat{[]uint{3}} out := &Nat{[]uint{0}} out.Exp(x, []byte{12}, m) expected := &Nat{[]uint{1}} if out.Equal(expected) != 1 { t.Errorf("%+v != %+v", out, expected) } } func TestExpShort(t *testing.T) { m := modulusFromBytes([]byte{13}) x...
