<backtrace>

Start by reproducing pnpm tauri build on Windows with rustc 1.92.0 for the reported Tauri project, then inspect the panic at ar_archive_writer-0.5.1/src/archive_writer.rs:496:14 and the rustc_codegen_ssa::CrateInfo archive-linking path. Done means the reported Windows build no longer triggers this compiler ICE, ideally with a smaller reproduction than the current project build.
