Use case
Can you share more information about the system you're running this on? The error indicates getrandom(2) isn't supported, and that would be needed to understand why.
@tuhaolam closing as can't reproduce but feel free to re-open with more info
I found that the reason is my host(centos 7.2 final) not support getrandom syscall, as https://stackoverflow.com/questions/30800331/getrandom-syscall-in-c-not-found shows. And this feature supports after v1.34.0.
