From 1e3fc7dcfae209ab511eb5194d626de021be69e7 Mon Sep 17 00:00:00 2001 From: naruse Date: Fri, 1 Jul 2016 19:37:43 +0000 Subject: * regcomp.c (noname_disable_map): don't optimize out group 0 Ruby's Regexp doesn't allow normal numbered groups if the regexp has named groups. On such case it optimizes out related NT_ENCLOSE. But even on the case it can use \g<0>. This fix not to remove NT_ENCLOSE whose regnum is 0.
