Exemplo

#include <regex>
#include <iostream>
 
int main()
{
    try {
        std::regex re("[a-b][a");
    } catch(const std::regex_error& e)
    {
        std::cout << "regex_error caught: " << e.what() << '\n';
        if(e.code() == std::regex_constants::error_brack)
              std::cout << "The code was error_brack\n";
    }
}

Output:

regex_error caught: The expression contained mismatched [ and ].
The code was error_brack
