Created attachment 889274 [details] build.log [ebuild N ] net-news/newsboat-2.30.1 USE="-debug" Compile time error "cannot find struct, variant or union type `LineColumn` in crate `proc_macro`". Seems to be fixed upstream in r2.33 and above.
Created attachment 889275 [details] emerge --info
Some observations about this bug (though I don't really understand much about the code base at hand..): How to reproduce: emerge -1 dev-lang/rust[nightly] (tested with dev-lang/rang-1.77.1) emerge =net-news/newsboat-2.30.1 Compilation of `proc_macro` with nightly compiler and --features span-locations succeeds with v1.0.60+/e31d61910049e097afdd3d27c37786309082bdcb (gh:dtolnay/proc-macro2). I guess, dropping 2.30.1 will make this bug obsolete, since newsboat-2.34 depends on proc-macro2-1.0.67.
