Issue #10734 has been updated by Hans Mackowiak.


if i use ruby2.2.0 it does happen for me too ...
and it seems it some kind of stack loop error because it seems to repeat itself

i tested it against ruby-head and there it seems the problem is fixed but not backported yet


----------------------------------------
Bug #10734: Segfault when combining default arguments with keyword arguments
https://bugs.ruby-lang.org/issues/10734#change-50958

* Author: Martin Natano
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
Combining default arguments with a keyword argument produces a segfault when the function is called with hash that contains a string key.
See the following transcript:

~~~
natano@ketzer:~$ irb
2.2.0 :001 > def foo(data=nil, foo: :bar)
2.2.0 :002?>   end
 => :foo 
2.2.0 :003 > foo({'foo' => 'bla'})
(irb):3: [BUG] Segmentation fault at 0x00000000000010
ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-linux]
