This is with the rust 1.91.0 beta from 20251009 and github.com/rust-lang/rust from b93730ce97c738bdb9209aa973d3fc6fd4ce1d81.

Reproduce the failure with cargo build --jobs 1 in the Ruffle checkout using the reported rustc versions and commits. Inspect wgpu-hal-26.0.6/src/gles/egl.rs:928 and the rustc_codegen_gcc behavior around the reported libgccjit call, then establish whether the failure is a compiler regression or dependency interaction; done means documenting a reproducible resolution or compatibility finding.
