Description
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.
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.

This is still crashing in Ruby 2.5.3. Is this going to ever be fixed in Ruby 2.5 series?

- Backport changed from 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN to 2.3: DONTNEED, 2.4: DONTNEED, 2.5: REQUIRED
Sorry, I've missed filling the Backport.
