From dc2d359b70725e890eff902e25bc0176245b0784 Mon Sep 17 00:00:00 2001 From: rhe Date: Tue, 20 Dec 2016 07:32:23 +0000 Subject: re.c: consider the case of RMatch::regexp is nil Follow r49675, r57098 and r57110. Don't assume RMatch::regexp always contains a valid Regexp instance; it will be Qnil if the MatchData is created by rb_backref_set_string().
