I have no experience with boost::process, only one idea:

Maybe the apostrophs around the password are normally eaten by the Linux 
shell, and you have to leave them out when building your arguments?

 Â Â  // connection info
 Â Â  args.push_back("-h127.0.0.1");
 Â Â  args.push_back("-utestuser");
 Â Â  args.push_back("--password=!@#QWE123qwe");Â Â Â  // <=
 Â Â  args.push_back("-P3306");

Freundliche Grüße * Best regards * Met vriendelijke groeten * Meilleures 
salutations
