Libfastjson API permits to access sublevel elements inside a tree, but will fail upon free of upper level elements if sub-level have been removed. This has been inherited from json-c and cannot totally be changed. However, it is often source of confusion and results in hard to find bugs.
We should try to harden the code so that it makes it easier to detect and report API misuse.
