* Target version: 
* ruby -v: 2.5.0, 2.5.1, 2.6.0dev (2018-09-07 trunk 64656)

----------------------------------------
The following code produces segmentation faults in Ruby 2.5.0, 2.5.1, and 2.6.0dev (2018-09-07 trunk 64656). This code worked in Ruby 2.4.1.

~~~ ruby
test_proc = Proc.new { "test" }
def foo(bar: 1, &block)
  yield
end
foo(**{}, &test_proc)
~~~

I've attached the crash reports for both Ruby 2.6.0dev (2018-09-07 trunk 64656) and 2.5.1. Let me know if there's anything else I can provide.
