Thread name with null crashes with "Illegal instruction"

[diwic]

Trying the following example on playpen (notice the \0 inside the thread name)

fn main() {
    std::thread::Builder::new().name("chi\0ld1".to_string()).spawn(|| {
        println!("Hello, world!");
    }).unwrap().join().unwrap();
}

Playpen output:

thread '<unnamed>' panicked at 'thread name may not contain interior null bytes', ../src/libstd/sys/unix/thread.rs:90
note: Run with `RUST_BACKTRACE=1` for a backtrace.
fatal runtime error: Could not unwind stack, error = 5
playpen: application terminated abnormally with signal 4 (Illegal instruction)

Both on stable and nightly.

It can be closed, right?

Yep

I was leaving it open because I did not know if it was going to be beta nominated or not.
