[ICE] Compiling the select crate

[Razican]

Dear community, I tried to run the following command in a code I'm writing:

cargo test --verbose --jobs 1 --release

And once it gets to the select 0.4.2 crate, I get this error (with its backtrace:

Running `rustc --crate-name select /path/to/.cargo/registry/src/github.com-1ecc6299db9ec823/select-0.4.2/src/lib.rs --crate-type lib --emit=dep-info,link -C opt-level=3 -C metadata=41536284123e2f65 -C extra-filename=-41536284123e2f65 --out-dir /path/to/target/release/deps -L dependency=/path/to/target/release/deps --extern html5ever=/path/to/target/release/deps/libhtml5ever-e6a9fd68468b9aa4.rlib --extern bit_set=/path/to/target/release/deps/libbit_set-9e3f9fcab576f1bf.rlib --cap-lints allow`
error: internal compiler error: unexpected panic

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

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

note: rustc 1.24.0-nightly (dc39c3169 2017-12-17) running on x86_64-unknown-linux-gnu

note: run with `RUST_BACKTRACE=1` for a backtrace

Let me know if I could help you with further information.
