Review comment:
How safe is the saving and re-throwing of the exception? Is there any
potential for `OutOfMemoryException& e` to be a reference to a base class?
Could `e` end up being truncated as a result? A direct `throw` to rethrow the
existing exception might be safer overall, and avoid the need for a goto.
Could we achieve the same effect with a higher-level try/catch block within
the function, and avoid the saving of the exception and the goto?
