[ndnSIM] [EXT] Unsupported EC key length

Hi Junxiao,

Thanks for your reply.
I tried to use the following command to diagnose my problem as your
suggestion: ./waf --command-template="valgrind --leak-check=full
--show-reachable=yes --log-file=error %s" --run ndn-simple
and get this output file
which shows that this program has 35 error from 18 contexts.

However, I run the same command on unmodified ndnSIM, its output file
129 error from 5 context.
I'm so confused

Sincerely yours,
Walter Swift
