In C++, object constructors throw exceptions if an object can't be instantiated properly. Normally, this does not cause any issues. An exception originating from an object constructed on the stack, or an object created dynamically using the new keyword, can be handled by the try-catch block around the code where the object was created.
It gets more complicated for static objects, though. Such objects are instantiated before the execution enters the main function, so they cannot be wrapped in a try-catch block of the program. The C++ compiler handles this situation by calling the std::terminate function, which prints an error message and terminates the program. Even if the exception is non-fatal, there is no way to recover.
There are several ways to not get into this pitfall. As a general rule, only simple, integral data types should be allocated...
