[boost] regex partial match bug

The following program demonstrates what we believe is a bug in regex partial
match algorithm:

    int main()
    {
    //  boost::regex const re("(ab)?c"); // ok
        boost::regex const re("(ab)?"); // fails in the assert below

        boost::cmatch what;
        assert(boost::regex_match( "a", what, re, boost::match_default |
boost::match_partial ));
    }

Is there an easy way to fix this?
