Initialize a static vector with vec!() leads to rustc failure.

```
rustc 0.11-pre (7056f97 2014-04-03 22:06:50 -0700)
host: x86_64-unknown-linux-gnu
```

Code:

``` rust
static A: Vec<uint> = vec!(1);
```

Error:

```
<std macros>:4:13: 4:47 error: internal compiler error: no type for local variable 31u32
<std macros>:4         let mut _temp = ::std::vec::Vec::new();
```
