Hi @paxifaer, thanks for your contribution.
Our current CI pipelines don't work properly with external contributions.
I've replicated your fix in this branch, and added a commit to test it in Ubuntu 20.04 (in which gcc default version installed is 9). The CI results can be checked here.

Will you merge into master?

[paxifaer]

Your way of submitting code is very cool! But I don't know if I am doing it correctly, please help me check it.

[JesusPoderoso]

There are still some missing suggestions to be applied @paxifaer.
Thanks for your effort!
