RUSTFLAGS="-Zmir-opt-level=3" cargo +master-stage1 b --release --all-features
building a download of futures-util v0.3.26 (found trying to install the latest cargo-lambda)
Meta
This uh doesn't reproduce on current nightly, because the ICE is from a debug assertion. My master-stage is a stage1 build of commit 44cfafe2fafe816395d3acc434663a45d5178c41, with debug assertions enabled. The assertion is here:
rust/compiler/rustc_mir_transform/src/lib.rs
Line 629 in bb18388
