I tried this code:

std::thread::spawn(move || {
  .....
})

I expected to see this happen: spawn new thread

Instead, this happened:

thread 'main' panicked at /work/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/std/src/thread/mod.rs:729:29:
failed to spawn thread: Os { code: 22, kind: InvalidInput, message: "Invalid argument" }

Upon further investigation using strace, it appears that the clone system call is being made with an invalid argument. Specifically, the parent_tid parameter is being passed as a pointer to tid, which seems to be incorrect.
