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

The new operator, and new[] operator should throw std::bad_alloc, but this is not always the case as the behavior can be sometimes overridden.

One can use std::set_new_handler and suddenly something entirely different can happen than throwing std::bad_alloc. Although the standard requires that the user either make memory available, abort, or throw std::bad_alloc. But of course this may not be the case.

Disclaimer: I am not suggesting to do this.
