[ruby-core:115961] [Ruby master Bug#20095] Regex lookahead behaving strangely in 3.3.0

Issue #20095 has been updated by dentarg (Patrik Ragnarsson). Same as https://bugs.ruby-lang.org/issues/20083? ---------------------------------------- Bug #20095: Regex lookahead behaving strangely in 3.3.0 https://bugs.ruby-lang.org/issues/20095#change-105919 * Author: sisyphus_cg (Sisyphus CG) * Status: Open * Priority: Normal * ruby -v: 3.3.0 * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- Multiple regex lookaheads seem to behave strangely in 3.3.0: ```ruby p "xxx" =~ /(?=.*x)x(?=banana)/ # 2 ``` Clearly, the string `xxx` does not contain `banana`, so this regex should never match, but it does. -- https://bugs.ruby-lang.org/
