Issue #19587 has been updated by nobu (Nobuyoshi Nakada). What does `described_class.extract` actually? ---------------------------------------- Bug #19587: Segmentation fault with ruby 3.2.0 - when running rspec suit. https://bugs.ruby-lang.org/issues/19587#change-102708 * Author: rubanthilak (Ruban Thilak) * Status: Open * Priority: Normal * ruby -v: 3.2.0 * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- The segmentation fault occurs when this particular regex match happens while running the entire Rspec test suit. ```ruby 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. ``` ruby /runner/_work/Event_Mgmt_Service/Event_Mgmt_Service/lib/regex/parser.rb:17: [BUG] Segmentation fault at 0x0000706c4c1ada0c ruby
