Description

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

str = "------------abcdefg------------#3895912"
re = /()\1\b\w*[a-zA-Z-]*\d+[\w-]{3,}\w+\b/
re.match?(str)

I accidentally left the "()\1" in the original post, but it should not be there and I don't see a way to change it. The code example should be:

str = "------------abcdefg------------#3895912"
re = /\b\w*[a-zA-Z-]*\d+[\w-]{3,}\w+\b/
re.match?(str)
