[Nfd-dev] New ndnSIM release and potential NFD bug investigation.

[Junxiao Shi]

Hi Spyros

The commit you cited occurs after 0.4.1 release and thus does not block you.

If you can reproduce the issue with latest NFD (0.5.0), can you write a
unit test on NccStrategy to reproduce the issue, and report it to NFD
Redmine site?

Yours, Junxiao
