Subject: [ruby-core:112486] [Ruby master Bug#19445] Segmentation fault with Numeric#step

Issue #19445 has been updated by hsbt (Hiroshi SHIBATA).


Thanks @nobu. I confirmed to fix this.

```
$ curl -s 'https://cache.ruby-lang.org/pub/misc/ci_versions/all.json' -o ruby_versions.json
  ruby -v -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 }"
ruby 3.3.0dev (2023-02-18T05:49:21Z master de7eb5e79a) +YJIT [arm64-darwin21]
-e:1:in `step': no implicit conversion to float from string (TypeError)
        from -e:1:in `each'
        from -e:1:in `map'
        from -e:1:in `<main>'
```

and also confirmed this issue happened with Ruby 3.0, 3.1 and 3.2.

----------------------------------------
Bug #19445: Segmentation fault with Numeric#step
https://bugs.ruby-lang.org/issues/19445#change-101929

* Author: hsbt (Hiroshi SHIBATA)
* Status: Closed
* Priority: Normal
* Backport: 2.7: DONTNEED, 3.0: REQUIRED, 3.1: REQUIRED, 3.2: REQUIRED
----------------------------------------
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`.
