[ruby-core:116687] [Ruby master Bug#20262] Regex mismatch between Ruby 3.2.2 and 3.3.0

Issue #20262 has been reported by weilandia (Nick Weiland). ---------------------------------------- Bug #20262: Regex mismatch between Ruby 3.2.2 and 3.3.0 https://bugs.ruby-lang.org/issues/20262 * Author: weilandia (Nick Weiland) * Status: Open * Priority: Normal * ruby -v: 3.3.0 * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- This might be a duplicate of https://bugs.ruby-lang.org/issues/20098, but I cannot make it match with the backref so maybe not. Below example matches in 3.2.2 but not in 3.3.0 ``` ruby str = "------------abcdefg------------#3895912" re = /()\1\b\w*[a-zA-Z-]*\d+[\w-]{3,}\w+\b/ re.match?(str) ``` -- https://bugs.ruby-lang.org/
