C benchmark PingPong is broken

[cmnrd]

The C version of PingPong prints the following error message and returns with a non-zero exit code.

Pong expected to receive 1000000 inputs, but it received 12000000.

The benchmark implementation looks correct to me, and it used to work in the past. Therefore, I assume that there is a bug in the code generator and/or the c runtime.

This is fixed in the benchmark-updates branch. It is a bug in the benchmark. I just didn't merge it because I figured that more problems would probably turn up.

[cmnrd]

I see. Should we get this branch merged then? Do you want to open a PR?
