Dear all,  
I updated my packages, and precompiling Caesar now fails. It worked a few weeks ago. I am using Julia 1.1 on Linux (Ubuntu 18.04), 64 bits.

Any idea?

Nobody has an idea?  
Shall I create an issue? 🤔

I’m running into a different issue during precompile with the latest released version, but I don’t get any errors when I `dev` Caesar in a new project.

I don’t think Dehann and `GearsAD` are very active on Discourse, so that’s probably a good idea.
