[Paparazzi-devel] Failing build check only in Semaphoreci and in unrelated code.

[Chris]

Hi.
I am trying to complete a pull request but my repository fails one check only on Semaphoreci.
The error does not have anything to do with my code and i am at loss to understand what is wrong.
The same aircraft and the whole build succeeds in Travis CI...

HERE IS THE FAILING OUTPUT.
