Or, we can do what I did in VTK. Use a file scope smart pointer that deletes the pointer.
Since the bug was assigned to me, I have checked in the above fix.
(atexit is too platform specific.)

Technically this is not a memory leak, since the memory is definitely allocated only once and is released by OS when the application quits. It is however a bit annoying, when searching for true memory leaks caused by bugs in other parts of code.

<dd>I noticed that the ObjectFactoryBase does not release the allocated
member m_RegisteredFactories when the application finishes. Technically
this is not a memory leak, since the memory is definitely allocated only
once and is released by OS when the application quits. It is however a
bit annoying, when searching for true memory leaks caused by bugs in
other parts of code.</font>

<dd>Is this behavior by design, or is it a bug (feature???) in
ObjectFactoryBase?</font>

<dd>The above problem can be eliminated quite easy by using the atexit
function, but I might not be aware of all the consequences. It seems to
