Code

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

debug_assert!(!body.has_free_regions(), "Free regions in optimized MIR");

Error output

error: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.69.0-dev running on x86_64-unknown-linux-gnu

note: compiler flags: --crate-type lib -C opt-level=3 -C embed-bitcode=no -Z mir-opt-level=3

note: some of the compiler flags provided by cargo are hidden

Check for free regions in MIR validation

This turns rust-lang#108720 into a MIR validation failure that will reproduce without debug-assertions enabled.
