It complains about missing third-party header "fmt/format.h".
Even after figuring out what that is and installing it, I can't get your project to build on a known-good compiler.

I am not asking for a reduced reproducer, just a preprocessed one. You can do that by appending "-gen-reproducer" to your command line, then attach those generated files to a new issue report on this project.
