Release Notes:

Hide
Due to an implementation detail, the <regex> header will never throw an exception corresponding to std::regex_constants::error_ctype. This can be exhibited from the below code sample:

#include <regex>
int main(void) {

  try {
    std::regex e("[[:not_a_class:]]", std::regex_constants::ECMAScript);
    std::regex_match("a", e);
  }
  catch(std::regex_error e){
    // e.code() will not be std::regex_constants::error_ctype
  }
  return 0;
}
