The aarch64 ABI says that only the first 8 arguments should be passed as registers, subsequent arguments should be put on the stack. Syscall9 is not putting the 9th argument on the stack, and it should. The standard library hasn't hit this issue because it uses Syscall9 for functions that only require 7 or 8 parameters.
