> When searching for regex "(a)(?:b)" with the nosubs flag set, perl_matcher
cores with failed assertion "m.subs() > 2" in >perl_matcher.hpp,
match_results::set_second().
Confirmed: the patch that's going into cvs is at the end, if you don't want
to apply that then, pass match_nosubs to the matching algorithm in place of
compiling with nosubs.
John.
