I haven't looked it in detail but it won't work as you
expected. flex compains as the following for v12 patch.

syncgroup_scanner.l:80: warning, rule cannot be matched
syncgroup_scanner.l:84: warning, rule cannot be matched

They are warnings about the patterns [1-9][0-9]* and {asterisk}
because it is matched by {node_name}+. The latter would no harm
(or the pattern is useless) but the former will make '1[a,b,c]'
to fail.
