I can reproduce that result with ./mach test-unit -p net cookie_http_state::test_, but not any more specific subset of the cookie_http_state tests.

Running /Users/joshmatthews/src/servo-master/target/debug/deps/main-1b00b47eb6a70d9e 'cookie_http_state::test_' does not reproduce the crash.

Aha! When I run with cargo test directly without RUST_BACKTRACE=1, it works. When I add RUST_BACKTRACE=1, it segfaults.

The only change to the libbacktrace in use in libstd between the 3/16 rustc nightly and the 4/9 nightly is rust-lang/rust@64a8c8a#diff-1a7024d46c31d728a04d5e0cafd98df8 (based on https://github.com/rust-lang/rust/commits/3712e11a828af2eea273a3e7300115e65833fbc5/src/libstd/Cargo.toml).

Disable RUST_BACKTRACE in unit tests on macOS. This works around #26192 which is a new relatively frequent intermittent crash on CI.
