malloc: *** error for object 0x10b5c62f8: pointer being freed was not allocated

[carllerche]

The following code when compiled on rust master then executed crashes with the error: "malloc: *** error for object 0x10b5c62f8: pointer being freed was not allocated"

struct Foo<T>;

fn foo<T>() -> ~Foo<T> {
  ~Foo
}

fn crash<T>(_: Option<T>, _: &Foo<T>) {
}

pub fn main() {
  crash(None, foo::<&str>());
}

My rustc info:

rustc 0.11-pre (2db9700 2014-04-07 08:56:34 -0700)
host: x86_64-apple-darwin

Edit: I guess my rustc is a day out of date. I am pulling latest master to double check.

I would suspect that de2567d fixes this, but I don't have a compiler on hand to verify

It's indeed fixed by de2567d.
