Issue #14627 has been updated by mame (Yusuke Endoh).


I could repro:

```
$ ruby -e 'Class.new.class_eval "def f(a:, N:)\nend"'
-e:1: [BUG] Segmentation fault at 0x0000000000000028
ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-linux]

*snip*
```

This [BUG] does not occur on trunk, so maybe it has been already fixed.

----------------------------------------
Bug #14627: class_eval "def foo(N:)\n end" regression
https://bugs.ruby-lang.org/issues/14627#change-71280

* Author: ViugiNick (Nickolay Viuginov)
* Status: Feedback
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: 2.5.0
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
Ruby crashes with a segfault in case of `class_eval` defining method with a keyword starts with a capital letter. It seems like it's a regression of one of the latest versions.
