Date: Wed, 24 Apr 2024 08:12:42 +0000 (UTC) [thread overview]

In-Reply-To: redmine.issue-20262.20240213062811.53206@ruby-lang.org
Issue #20262 has been updated by mame (Yusuke Endoh).
Status changed from Open to Closed
Maybe the same issue as https://bugs.ruby-lang.org/issues/20083. Fixed at 3.3.1.
```
$ RBENV_VERSION=3.2.2 ruby -e 'str = "------------abcdefg------------#3895912"
re = /\b\w*[a-zA-Z-]*\d+[\w-]{3,}\w+\b/
p re.match?(str)'
true
$ RBENV_VERSION=3.3.0 ruby -e 'str = "------------abcdefg------------#3895912"
re = /\b\w*[a-zA-Z-]*\d+[\w-]{3,}\w+\b/
p re.match?(str)'
false
$ RBENV_VERSION=3.3.1 ruby -e 'str = "------------abcdefg------------#3895912"
re = /\b\w*[a-zA-Z-]*\d+[\w-]{3,}\w+\b/
p re.match?(str)'
true
```
----------------------------------------
Bug #20262: Regex mismatch between Ruby 3.2.2 and 3.3.0
https://bugs.ruby-lang.org/issues/20262#change-108083
* Author: weilandia (Nick Weiland)
* Status: Closed
* 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)
```
