----------------------------------------
Bug #19445: Segmentation fault with Numeric#step
https://bugs.ruby-lang.org/issues/19445#change-102493

* Author: hsbt (Hiroshi SHIBATA)
* Status: Closed
* Priority: Normal
* Backport: 2.7: DONTNEED, 3.0: REQUIRED, 3.1: DONE, 3.2: DONE
----------------------------------------
The following commands will cause a segmentation fault.

```
curl -s 'https://cache.ruby-lang.org/pub/misc/ci_versions/all.json' -o ruby_versions.json
ruby -rjson -e "min = JSON.parse(File.read('ruby_versions.json')).sort.first; p 2.2.step(by: 0.1, to: min).map{|v| v.round(1).to_s }"
```

Note: above code is working with `min.to_f` instead of `min` in `Numeric#step`.
