Most likely the issue is because of two things: You're splicing your array inside a loop that iterates over said array forwards. If you're going to do this, you should iterate backwards so it doesn't mess up the index. For example, let's say zombieCount has 3 elements. The first iteration...

May I modify the value of an exception inside a std::exception_ptr?
c++,exception,c++11,exception-handling
Your code is conforming and portable. But there be dragons here: If you obtain your exception_ptr via current_exception(), it is unspecified whether you get a reference to a copy of the current exception, or a reference to the current exception itself. Even if you call current_exception() twice in a row,...
What is the purpose of RAISE_APPLICATION_ERROR?
raise_application_error does more than print an error message to the console (like dbms_output.put_line does). First, it's an actual error - it fails the statement, terminates the current block's execution, and propagates to outer blocks (similar to throw in Java or raise in Python). Second, it actually returns this error regardless...

When writing a custom iterator, how can I avoid the compiler generating a Reset() method that throws an exception?
Nope, you can't. The assumption that the state machine can be reset does hold for your simple case, but be aware you can write iterators with side effects, and the compiler cannot assume the state machine is pure in the general case. So the safe bet is to simply disallow...
