Rule 7-5-3 and storing a reference for later use

[misra cpp]

We agree with your interpretation of 7-5-3, and we recognise the limted scope of the current rule

We are currently working on a new version of the standard, and the aim for this rule is that we move toward the requirements of MISRA C:2012 18.6 'The address of an object ... shall not be copied to another object that persists after the first object has ceased to exist'
