Bug #19476: Regexp unexpected partial match

https://bugs.ruby-lang.org/issues/19476#change-102160



* Author: andreccosta (Andr=E9 Costa)

* ruby -v: ruby 3.2.1 (2023-02-08 revision 31819e82c8) [arm64-darwin22]

* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN

----------------------------------------

This regular expression does not have the expected match since Ruby 3.2.





Ruby 3.2.1:



```ruby

> RUBY_VERSION

=3D> "3.2.1"

> "123456789".match(/(\(?\d-?\)?){6,15}/)

=3D> #<MatchData "123456" 1:"6">

> "123456789".match(/(\d-?\)?){6,}/)

=3D> #<MatchData "123456" 1:"6">

```



Results in a partial match even though the specified quantifiers should all=
ow matching the whole string.



Ruby 3.1.3:



``` ruby

> RUBY_VERSION

=3D> "3.1.3"

> "123456789".match(/(\(?\d-?\)?){6,15}/)

=3D> #<MatchData "123456789" 1:"9">

> "123456789".match(/(\d-?\)?){6,}/)

=3D> #<MatchData "123456789" 1:"9">

```



Which is the outcome for both patterns in previous versions.
