Bug #20095: Regex lookahead behaving strangely in 3.3.0

https://bugs.ruby-lang.org/issues/20095#change-106509



* Author: sisyphus_cg (Sisyphus CG)

* Status: Closed

* Priority: Normal

* ruby -v: 3.3.0

* Backport: 3.0: DONTNEED, 3.1: DONTNEED, 3.2: DONTNEED, 3.3: REQUIRED

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

Multiple regex lookaheads seem to behave strangely in 3.3.0:



```ruby

p "xxx" =3D~ /(?=3D.*x)x(?=3Dbanana)/ # 2

```



Clearly, the string `xxx` does not contain `banana`, so this regex should n=
ever match, but it does.
