I think that LRM 13.11 might apply here (coming from LRM 4.8),

"If Storage_Pool is not specified for a type defined by an
  access_to_object_definition, then the implementation chooses
  a standard storage pool for it in an implementation-defined
  manner.  In this case, the exception Storage_Error is raised
  by an allocator if there is not enough storage."

A handler then, if possible, could be of the kind that
does not require additional resources for its execution.
It might be more tricky to use one with tasks, but IIUC,
one can attach termination handlers.
