Sometimes this happens the very first time I try to execute the command, some other times I have to try a couple of times to see that Segmentation Fault (but usually within the first 5 attempts).

Is duplicate of Ruby - Bug #19587: Segmentation fault with ruby 3.2.0 - when running rspec suit.ClosedActions

Interesting indeed.

I tested this briefly in a standalone .rb file; first I got
"Aborted (core dumped)", then lateron I got:

false

(Content of that .rb file was simply:)

puts /^((a|c)|\s?){1,3}$/.match?('abc')

It's interesting that this shows a different behaviour. Perhaps
if someone has time, it may be helpful for others to learn
something and explain why this leads to a segfault sometimes
and to no segfault at other times.

It seems reproducing only on IRB, but not without IRB.

$ ruby3.2 -v -e 'p 1000.times.any? {/^((a|c)|\s?){1,3}$/.match?("abc")}'
ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-darwin22]
false

And does not with 3.3.

Actually initially I had the problem running my rspec on Rails 7.0.8.
I reported here the easiest reproducible example.

Here is a script to reproduce the same in rails/rspec:

# frozen_string_literal: true

require "bundler/inline"

gemfile(true) do
  source "https://rubygems.org"

  git_source(:github) { |repo| "https://github.com/#{repo}.git" }

  gem "rails", "= 7.0.8"
  gem "rspec"
end

require "active_record"
require "rspec/autorun"

class TestCase
  def matching?(string)
    /^((a|b|c)|\s?){1,3}$/.match?(string)
  end
end

describe TestCase do
  it 'should work' do
    expect(described_class.new.matching?('abc')).to be true
  end

  it 'should not work' do
    expect(described_class.new.matching?('xyz')).to be false
  end
end
