still crashes in the latest 2.6. Any chance it can be backported?

Repro:
require "ripper/sexp" rip = Ripper::SexpBuilderPP.new "_, _, _ = 1, *2, *3" rip.yydebug = true rip.parse

(seems to work on 2.5 just fine)

Thank you for pointing this out. I have confirmed the snippet reproduces SEGV with 2.6.6 on my laptop.
I will fill the Backport field and close this ticket to notice stable branch maintainers.

I just find that e39f7e64b73f0506def7adc88226d6821608da54 (r67305) is included in ruby_2_7.
