Bug #10543: ruby -c and ripper inconsistency: /(?<n>a(b|\g<n>))/

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 2.2.0dev (2014-11-26 trunk 48577) [x86_64-linux]
• Backport: 2.0.0: DONTNEED, 2.1: DONTNEED

以下のように、/(?a(b|\g))/ というだけのソースは
ruby -c では問題無しとなりますが、
Ripper.sexp では構文木でなく nil が返ってきてしまいます。

% cat z.rb                   
/(?<n>a(b|\g<n>))/
% ./ruby -c z.rb
Syntax OK
% ./ruby -rripper -e 'p Ripper.sexp(STDIN.read)' < z.rb  
nil
% ./ruby -v
