Definition: dangling reference

A link or pointer to something (instruction, table element, index item, etc.) that no longer contains the same content. If the reference is not a currently valid address, or if it is a valid address but there is no content in that location, it may cause the computer to crash. If the content has changed, it can also cause the system to crash, or, at the very least, produce erroneous output.
