Initialize variables in FFI tests

Browse source 
These ones are used to compute averages. If they are not initialized to
zero, they might contain some garbage. In fact, they almost always do
on platforms other that x86_64, failing the FFI tests. If optimizations
are enabled, these tests usually fail on x86_64 too. The reason this
went unnoticed is contrived set of coincidences.
