[ruby-core:81254] [Ruby trunk Bug#13324][Closed] IRB Segmentation Fault from eval infinite loop

Issue #13324 has been updated by ko1 (Koichi Sasada).

Status changed from Open to Closed

Fundamentally, we can't control machine stack overflow.
We will improve the situation (but can't solve completely).

Bug #13324: IRB Segmentation Fault from eval infinite loop
https://bugs.ruby-lang.org/issues/13324#change-64915

* Author: [e-mail] (Sean Rodman)
* Status: Closed
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-darwin15]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
I am not sure if this has already been taken care of or not but I am using ruby 2.3.0 and irb 0.9.6(09/06/30) and when I run the below code I get a segmentation fault

```ruby
a = "eval a"; eval a
```
when running the same code with just the ruby interpreter I get the below error which is what I would expect

```
-e:1:in `eval': stack level too deep (SystemStackError)
	from (eval):1:in `<main>'
	from (eval):1:in `eval'
	from (eval):1:in `<main>'
	from (eval):1:in `eval'
	from (eval):1:in `<main>'
	from (eval):1:in `eval'
	from (eval):1:in `<main>'
	from (eval):1:in `eval'
	 ... 9507 levels...
	from (eval):1:in `eval'
	from (eval):1:in `<main>'
	from -e:1:in `eval'
	from -e:1:in `<main>'
```
