No-one sane writes parsers any more. People use parser generators.

GCC uses a hand-written parser. So does the C# compiler for .NET. V8 and, as far as I know, the other browsers' JS implementations have hand-written parsers. Dart (both the VM and the self-hosted dart2js compiler) have hand-written parsers.

Offhand, I'm not aware of any real-world language with lots of users that has a generated parser.
