When the position at which to insert the character is large, the position will overflow, leading to a buffer underwrite.

If a string is already very large, combining it with more input can cause a hidden overflow in the size calculation. This makes the system think it has enough memory when it doesn't. As a result, data may be written past the end of the allocated memory, leading to crashes or memory corruption.
