Passing 1 or :a as a kwargs splat to a c-lang defined method causes segmentation fault. (It was a TypeError in ruby 2.6.0)

p **1
p **:a
rand **1

Passing it to an user-defined method won't cause segv, but it was a TypeError in ruby 2.6.0

def p2*;end
p2 **1 # nil (TypeError in ruby 2.6.0)
p2 **:a # nil (TypeError in ruby 2.6.0)

# these are ok
a=1; p **a # TypeError
a=:a; p **a # TypeError
def p2*;end
a=1; p2 **a # TypeError
a=:a; p2 **a # TypeError
