This fails in a cryptic way for asan, lsan and ubsan. Seen on llvm 10.0.1-rc1,
but IIUC not on llvm 10.0.0.

It seems to reproduce on llvm 10.0.0, so it's likely an environment issue.

Could it be related with the issue I fixed with 0ad3cb8c267516b96f205d03b5284b7d3d507729, where getrandom might not be supported by the kernel?
