I filed it and other failures to https://gist.github.com/hsbt/ea3e52d9fb52aed58d25caf839eae5ff

@katei (Yuta Saito) found this issue caused by YJIT and rustc 1.71.0. It's not happend with

../ruby/configure -C --disable-install-doc --with-openssl-dir=/opt/homebrew/opt/openssl@1.1 --with-readline-dir=/opt/homebrew/opt/readline --with-libyaml-dir=/opt/homebrew/opt/libyaml RUSTC='rustc +1.70.0'

But RUSTC='rustc +1.71.0' is failed with same error on macOS Sonoma(beta) and Ventura.
