#### Description

While running the steps from the readme for the [examples/ccn-lite-relay](https://github.com/RIOT-OS/RIOT/tree/master/examples/ccn-lite-relay) application on native, a floating point exception is raised. I tried building in Docker and I get the same issue. Current master pointing to 8e47621e7ce1c5eb6a6832ea2ab885c8f1df5d7a.

#### Steps to reproduce the issue

Run the ccn-lite-relay example and follow the steps from the example.

#### Expected results

The steps from the [readme](https://github.com/RIOT-OS/RIOT/tree/master/examples/ccn-lite-relay#example-setup) work and it is possible to follow the example steps from the readme.

#### Actual results

```
