Segfault with Ruby 3.3.0

[Charlie Savage]

I'm also experiencing this issue on macOS 14.2.1 (23C71) on Ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x86_64-darwin23]

Also tested against ruby 3.4.0dev (2023-12-25T09:36:28Z master a164a34110) [arm64-darwin23] compiled with --with-openssl-dir=/opt/homebrew/opt/openssl@3

It does not happen on 3.2.2 (which was compiled on a different version of macOS)

I have a reduced test case:

#!/usr/bin/env ruby -s
# frozen_string_literal: true

require 'bundler/inline'

gemfile do
  source 'https://rubygems.org'

  gem 'ruby-prof'
end

RubyProf::Profile.profile do
  Array.new # `Object.new` works, for example
end

Ruby has been compiled with options

rvm install 3.3.0 --with-openssl-dir=/usr/local/opt/openssl@1.1 --with-libyaml

Log

$ bundle exec ./test/profile.rb
