I was trying to build https://github.com/lovasoa/wikipedia-externallinks-fast-extraction

I am not sure whether this is important, but I launched cargo test, and in another terminal window cargo build --release (before cargo test completed).

The compiler crashed with :

Making the incriminated function public fixed the problem.

Reproduces on 1.29.0, fixed in 1.30.0.

If this can be reduced to a minimal example we could add a test, but we could also just close this as-is.
