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.

I can't reproduce it.

$ ruby -v -e 'Class.new.class_eval "def foo(N:)\n end"' ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-linux-gnu] Traceback (most recent call last):	1: from -e:1:in `<main>' -e:1:in `class_eval': (eval):1: formal argument cannot be a constant (SyntaxError) def foo(N:) ^~ (eval):1: dynamic constant assignment def foo(N:) ^

Could you post simple code to reproduce and full message, in text format?

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.
