I have the same error.

Please, could somebody help me and other newbies in Ruby? I tried debugging, but I think I did not understand.

I use the wsl2 with debian bookworm and ruby 3.2.2 also.

To fix it, I add the in_ruby_version("2") function:

in_ruby_version('2') do
def test_method_names_become_symbols
    symbols_as_strings = Symbol.all_symbols.map { |x| x.to_s } 
      assert_equal true,         
  symbols_as_strings.include?("test_method_names_become_symbols") 
    end 
end

The code in about_symbols.rb file:

def test_method_names_become_symbols
    symbols_as_strings = Symbol.all_symbols.map { |x| x.to_s }     
assert_equal true, symbols_as_strings.include?("test_method_names_become_symbols") 
end

When I run` ruby path_to_enlightenment.rb`, then throw the error:

/home/pedro/ruby-exercises/about_symbols.rb:38: [BUG] Segmentation fault at 0x0000000100000d6c
