Bug #19587

closed

Segmentation fault with ruby 3.2.0 - when running rspec suit.

Added by rubanthilak (Ruban Thilak) over 1 year ago. Updated over 1 year ago.

Target version:

ruby -v:
3.2.0
Backport:
3.0: DONTNEED, 3.1: DONTNEED, 3.2: DONE
[ruby-core:113165]

Description

The segmentation fault occurs when this particular regex match happens while running the entire Rspec test suit.

    it 'returns nil after timeout for untrusted regex' do
      extracted_value = described_class.extract('test1-test2-test3-test4-test_5', '^([0-9a-zA-Z\-/]*){1,256}$')
      expect(extracted_value).to be_nil
    end

But when I try to run only that particular spec file, segmentation fault does not occur.

    def extract(str, regex_str)
      regex = Regexp.new(regex_str, timeout: 1.0)
      regex.match?(str) ? str.match(regex) : nil
