Can a local variable's memory be accessed outside its scope? http://stackoverflow.com/questions/6441218/can-a-local-variables-memory-be-accessed-outside-its-scope byte in the storage is well known and in particular lifetimes of storages follow a nesting pattern. That is the allocation.. The relative order of the beginnings and endings of lifetimes of storages associated with local variables can be worked out.. easy to break them accidentally. I certainly have many times. And worse the problem often only surfaces when memory is detected..
