Description
Just updated rustc/clippy and have a crash in CI, running:
cargo clippy --manifest-path=druid/Cargo.toml --all-targets --features=image,im --target wasm32-unknown-unknown
against linebender/druid@ac936c2
I do not see this crash against the native target (I'm running macOS 10.14.6)
let me know if I can be more helpful.
