What is the difference between == and Equals() for primitives in C#?
...l call short.Equals(short) directly, without boxing. If age is larger than 32767, it will throw an overflow exception.
You could also call the short.Equals(object) overload, but explicitly pass a boxed object so that it gets the same type:
Console.WriteLine(newAge.Equals((object)(short)age)); // tru...

Specifically, what's dangerous about casting the result of malloc?
... when compiling in 64-bit mode, your returned pointer will be truncated to 32-bits.
