Upgrading from IDF 4.0.0 to 4.3.1 breaks build

[miniwin]

I have a project that isn't too complex. It has a main component and 2 other components. It's been building fine in IDF version 4.0.0. Upgrading to 4.3.1 and it fails to build with some unresolved externals when linking which are in my source code. The source files that contain the functions that are not found are being compiled - I tried putting deliberate errors in them and the compiler noticed. I can't figure out why the link is not including the correct object files, or finding the functions if they are.

I've tried removing the components and putting everything into a single main component - and everything builds, so I don't think there's anything wrong with the code.

The project is in github here...

Anyone any ideas?
