I will have a closer look but what I can say for the moment is that the tested
source code doesn't seem to match the latest trunk state, the line numbers
don't match. Can you have a check with latest version ?

For info, there is a check on the address of the key to avoid just what you
describe that is to say deallocate a node and keep on using the key part of it.
