Running on Ubuntu 20.04 Arm64 with Ruby 3.0.2 I'm getting a seg fault on what looks to be a free. See below for a stack trace:

Is this 100% reproducible? Can you include the code snippet that's causing the crash?

This is coming through using Capybara with a Selenium Chrome driver. The relevant code is as follows:

Capybara.default_driver = :selenium_chrome
Capybara.app_host = "https://instagram.com"
Capybara.default_max_wait_time = 15

module Zorki
  class Scraper
    include Capybara::DSL

    def login
      visit("/")
      # Check if we're redirected to a login page, if we aren't we're already logged in
      return unless page.has_xpath?('//*[@id="loginForm"]/div/div[3]/button')
    end
end

Specifically it's throwing the error at return unless page.has_xpath?('//*[@id="loginForm"]/div/div[3]/button')

FYI just attempted this with Firefox on the same machine, so it's definitely not related to the browser being used.

Further update: This seems to be an arm64 issue specifically. Running it on a Raspberry Pi running Debian Buster on an armHF works fine.

There's a possibility this could be caused from Parallels, which I'm using to run Ubuntu on a MacBook Pro M1, but that'd be exceptionally odd.
