[Amitava Shee]

I am getting a Bus error - please see the following.Should I file this as
an issue in github?

amitava:learn amitava$ cat app.rs
// vi:ts=4:sw=4:nu

fn main() {
// should not compile - infinite size, needs redirection
struct Foo {
child: OptionFoo
};

let c = Foo {child: None};
let p = Foo {child : Some(c) };
//printfln!(%?, p);
}

amitava:learn amitava$ make
rustc -Z debug-info -o app app.rs
app.rs:10:5: 10:6 warning: unused variable: `p` [-W unused-variable
(default)]
app.rs:10 let p = Foo {child : Some(c) };
  ^
make: *** [app] Bus error: 10

This is a known bug: https://github.com/mozilla/rust/issues/3779

The fix, which you probably realized, is to change OptionFoo to
Option~Foo or Option@Foo.

Cheers,
Tim
