Imagine a function that performs file I/O and may throw an exception. What might be a concern if this function is used inside a constructor, and how might it be addressed? 

If an exception is thrown during the construction of an object, that object's destructor will not be called since the object was never fully constructed. This can lead to resource leaks or other inconsistencies. It's crucial to ensure that if a constructor might throw an exception, all resources acquired up to that point are properly released to prevent such issues. Proper exception handling and resource management techniques, like RAII, are essential.
