I wonder if this is due to #18294, not #19104. @jeremyevans0 What do you think?

I'll see if I can fix it today. ---------------------------------------- Bug #19379: Regex: "end pattern with unmatched parenthesis" with Ruby 3.2 and interpolation https://bugs.ruby-lang.org/issues/19379#change-101524 * Author: renchap (Renaud Chaput) * Status: Open * Priority: Normal * ruby -v: ruby 3.2.0 (2022-12-25 revision a528908271) [arm64-darwin22] * Backport: 2.7: DONTNEED, 3.0: DONTNEED, 3.1: DONTNEED, 3.2: REQUIRED ---------------------------------------- Sample code: ``` r2 = %r{#c-\w+/comment/[\w-]+} %r{https?://[^/]+#{r2}}x ``` This works with Ruby 3.1: ``` irb(main):001:0> r2 = %r{#c-\w+/comment/[\w-]+} irb(main):002:0> %r{https?://[^/]+#{r2}}x => /https?:\/\/[^\/]+(?-mix:#c-\w+\/comment\/[\w-]+)/x ``` But fails with Ruby 3.2.0: ``` irb(main):022:0> r2 = %r{#c-\w+/comment/[\w-]+} irb(main):023:0> %r{https?://[^/]+#{r2}}x (irb):23:in `<main>': end pattern with unmatched parenthesis: /https?:\/\/[^\/]+(?-mix:#c-\w+\/comment\/[\w-]+)/x (RegexpError) ``` But if I dont use interpolation, it works correctly: ``` irb(main):001:0> %r{https?://[^/]+#c-\w+/comment/[\w-]+}x => /https?:\/\/[^\/]+#c-\w+\/comment\/[\w-]+/x ``` -- https://bugs.ruby-lang.org/
