Bug #20212
Updated by hsbt (Hiroshi SHIBATA) 10 months ago
Tried this with ruby 3.3.0, both irb and rails console are crashing
```ruby
DOMAIN_REGEX = Regexp.new(
/\A((?=.*?[a-z])(?!.*--)[a-z\d]+[a-z\d-]*[a-z\d]+).((?=.*?[a-z])(?!.*--)[a-z\d]+[a-z\d-]*[a-z\d]+).((?=.*?[a-z])(?!.*--)[a-zd]+[a-zd-]*[a-zd]+).((?=.*?[a-z])(?!.*--)[a-zd]+[a-zd-]*[a-zd]+)\Z/x
)
full_domain = "www.google.com"
100.times.each { full_domain.match(DOMAIN_REGEX) }
```
```
