Segfault on armhf

[oberstet]

This example works on both x86-64 and aarch64, but segfaults on armhf.

My first suspicion would be: a msgpack issue on 32 bit. We currently don't build x86-32, which would allow to bisect this.

So probably it makes sense to first fix this - moving to the latest msgpack library.
