Can the C++ `new` operator ever throw an exception in real life?

Question

Can the new operator throw an exception in real life?

And if so, do I have any options for handling such an exception apart from killing my application?

Answer 1

It's good to check/catch this exception when you are allocating memory based from something given from outside (from user space, network e.g.), because it could mean an attempt to compromise your application/service/system and you shouldn't allow this to happen.
