Hello,
I found an internal compiler error when compiling this pull request with rust nightly on github CI. See the CI output at https://github.com/image-rs/jpeg-decoder/pull/146/checks?check_run_id=773387154
Meta
rustc version: nightly-x86_64-unknown-linux-gnu installed - rustc 1.46.0-nightly (4fb54ed 2020-06-14)
Error output
error: internal compiler error: src/librustc_traits/normalize_erasing_regions.rs:37: could not fully normalize `<A as sealed::SimdArray>::Tuple`
