 Just to be clear here - if this is in a safety-critical system, and your allocation system returns nullptr, people die.  That is why you don't use this kind of thing for important tasks.
 

In this scenario, nullptr returned means the main region allocator is out of memory. So, pool things up where this never occurs.
