Code tested on https://wandbox.org/
--------------------------
#include <iostream>
#include <regex>
int main() {
std::regex re;
try {
// std::regex(R"(^[-\wa]$)"), std::regex(R"(^[\w-]$)")
// are ok for libc++
re = std::regex(R"(^[\w-a]$)");
} catch ( const std::regex_error& err ) {
// 1:The expression contained an invalid collating element name.
std::cout << err.code() << ':' << err.what() << std::endl;
std::abort();
}
