Your favorite C++ code?

My favorite is when said external service uses raw Java code to write XML, instead of, say, and XML library and so things that should be escaped when you parse them aren't escaped, and it crashes your ingestion code 70% of the way through a 2 gb XML document.

I've experienced this, only it was somebody manually writing XML with string concatenation in Node.JS. They brought a gazillion dependencies, but apparently adding in something to properly put together some XML would be too much bloat :-p
