Here's an example program that fails to compile with gcc-10 for me: https://gist.github.com/kevinushey/cfa848be2d39ddd110f893d9b6c5ac9c
So I think we can conclude this is a gcc-10 bug. It also fails with the contracts branch of gcc on godbolt (although with a different error): https://godbolt.org/z/dowsE5 But gcc trunk seems okay.
