Example cylinder2d memory leaks

Hi,

I just download Palabos today. And tried simply in showcase/cylinder2d

I did in the build folder:
cmake …
make
cd …/
./cylinder2d

then it gives me

No protocol specified

step 200; t=0.02; av energy =2.579491445e-05; av rho =0.9999993807

I get the same error, any updates?

I am running the case on the cluster.
