[ndnSIM] [EXT] debugging problem

[Junxiao Shi]

Hi Sai

The crash is most likely not caused by SimpleRefCount, but some other
component.
Error message suggests a double free error or memory leak.

If you haven't read ns-3 Reference Manual *in full*, you should do so to
gain a deeper understanding on how ns-3 works at low level.
