I would suggest using `ColorType::InheritParent` as it is clear what this variant will do. A `Option` does not make clear what happens when setting it to `None`: it could be...

I figured out that you have to return a `std::tuple` of a `std::map`: ```cpp std::map result; result["secret"] = secret; result["role"] = role; result["salt"] = salt; invocation->result (std::make_tuple (result)); ```

Ah thanks for the quick response! I'll look further into why `computePathLoss` is not called from there!

Okay, it looks like the `TwoRayGroundReflection` only overrides the `computePathLoss(const ITransmission *transmission, const IArrival *arrival)`. But the power functions seem to use the `computePathLoss(mps propagationSpeed, Hz frequency, m distance)` which...

The `ScalarAnalogModel` uses the `(transmission, arrival)` variant of `computePathLoss` whereas the attenuation functions always use the `(mps, Hz, m)` variant. This sounds like a bug to me, although I'm unsure...

How would you implement `TwoRayGroundReflection` with respect to the ground in the `(mps, Hz, m)` variant? I don't see how the transmitter and/or receiver altitude from the ground can be...

It seems like the altitude is obtained from the transmission and arrival position which are not available in the other variant. This means that that the ground projection must be...

The error happens when running `zbox-fail-test --file data check` in the previously forcefully stopped VM ([run-check.exp](https://github.com/fin-ger/zbox-fail-test/blob/master/scripts/run-check.exp)) The executable was automatically build by the [travis-ci configuration](https://github.com/fin-ger/zbox-fail-test/blob/master/.travis.yml). I am using the official...

I built a new version ([0.4.0](https://github.com/fin-ger/zbox-fail-test/releases/tag/v0.4.0)) that uses zbox from the current git master and added `RUST_LOG=zbox=trace` to the run and check action of the test ([run-test.exp](https://github.com/fin-ger/zbox-fail-test/blob/master/scripts/run-test.exp#L24), [run-check.exp](https://github.com/fin-ger/zbox-fail-test/blob/master/scripts/run-check.exp#L16)).

Okay, so if this is a qemu issue than it is not relevant for zbox. Have you tested failures of real machines with zbox?
