The first two times of call crypto.getRandomValues returns 0

This behavior always occurs

Yeah, I've noticed that one before. I believe that is because a 64-bit random number generator is used but only 32-bit seeds. Another problem is that after compilation, the series of random numbers is deterministic (this behavior is a bit harder to observe due to the lack of run-wasm)
