[ruby-core:118290] [Ruby master Bug#20572] Compilation hangs with nested until

Issue #20572 has been updated by kddnewton (Kevin Newton).


This is another example, I imagine because of the same source problem. It also works if you disable optimizations:

```ruby
_ = _ rescue while 1
end
```

```ruby

this code causes an infinite loop in the compiler.
