here is updated test. I wondered if maybe someone got the haystack and needle
swapped. no difference.

#include <regex>
#include <iostream>
int main(int argc, char * argv[]) {
       
std::cout<<std::regex_match("def",std::regex("abcdefg",std::regex_constants::extended))<<std::endl;
       
std::cout<<std::regex_match("abcdefg",std::regex("def",std::regex_constants::extended))<<std::endl;
        return 0;
}
