Corrupted initialization in the static struct

[lifthrasiir]

struct X { vec: &'static [int] }
static V: &'static [X] = &[X { vec: &[1, 2, 3] }];
fn main() {
    for V.each |&v| {
        io::println(fmt!("%?", v.vec));
    }
}

...should print &[1, 2, 3] but instead prints something like &[4492532864, 24]. It is pretty evident that the compiler messed up with the representation of [int, ..n] and [int] somehow, or at least failed to typecheck correctly.

@graydon: this looks similar to the static array problem you were dealing with before

[graydon]

Does, yes. But I pushed a fix last week. Can you reproduce on incoming?

[lifthrasiir]

@graydon I've tested the code with the recent master (5f13e9c 2013-04-02 13:36:51 -0700). I see dozens of commits in between but clearly the master itself is very new.

Reproduced with 84233c0 on 2013-05-20 09:34:44 -0700

This code now works:

struct X { vec: &'static [int] }
static V: &'static [X] = &[X { vec: &[1, 2, 3] }];
fn main() {
    for &v in V.iter() {
        println(fmt!("%?", v.vec));
    }
}

Flagging as needstest.
