[ruby-core:106962] [Ruby master Bug#18458] Segmentation fault when missing Warning#warn method

From: etienne <noreply@...>
Date: 2022-01-04 14:22:03 UTC
List: ruby-core #106962
Issue #18458 has been reported by etienne (テ液ienne Barriテゥ).

----------------------------------------
Bug #18458: Segmentation fault when missing Warning#warn method
https://bugs.ruby-lang.org/issues/18458

* Author: etienne (テ液ienne Barriテゥ)
* Status: Open
* Priority: Normal
* ruby -v: 3.1.0p0
* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
If you remove the `Warning#warn` method and call `Kernel#warn`, you get a segmentation fault:

ruby 3.1.0:
``` 
$ ruby -e 'Warning.undef_method(:warn); warn ""' 2>&1 | head -2                                                                                                                                                                                                                    
<internal:warning>:51: [BUG] Segmentation fault at 0x0000000000000010
ruby 3.1.0p0 (2021-12-25 revision fb4df44d16) [x86_64-darwin21]
```

It's not new, you get the same with 3.0.3:
```
$ ruby -e 'Warning.undef_method(:warn); warn ""' 2>&1 | head -2                                                                                                                                                                                                                    
<internal:warning>:51: [BUG] Segmentation fault at 0x0000000000000010
ruby 3.0.3p157 (2021-11-24 revision 3fb7d2cadc) [x86_64-darwin20]
```

In 2.7 though you get a NoMethodError exception:
```
$ ruby --disable-all -e 'Warning.undef_method(:warn); warn ""'
Traceback (most recent call last):
	1: from -e:1:in `<main>'
<internal:warning>:43:in `warn': undefined method `warn' for Warning:Module (NoMethodError)
```

(I disabled gems because rubygems core extensions adds two lines of backtrace, but it's the same result in the end)
