Fixes #13987.
Dynamic
Val::FixedLengthListlowering stored each element relative to the beginning of the canonical ABI allocation instead of the list's caller-provided base offset. When nested inside another
value, this could overwrite adjacent fields.This change includes the base offset when storing each element and adds a regression test for a fixed-length list nested inside a tuple.
Tests:
-
cargo test --test all component_model::fixed_length_list
-cargo test -p wasmtime --lib
-cargo clippy -p wasmtime -p wasmtime-cli --all-targets
