Crash on Win7 x86_64#70

Racer crashes using the latest x86_64 nightly.

Version info:
$ rustc --version
rustc 0.13.0-nightly (e09d98603 2014-11-18 23:51:43 +0000)

The (quite vague) crash output:
$ racer complete std::io::

task '<main>' has overflowed its stack

It should be noted that code doesn't compile on this nightly due to rust-lang/rust#18645

    Looks like #57 again.

    I don't think this is the same. It looks like globs connected to the new namespaced enums that's confusing it.
    Running with the debug logging on points at the 'pub use self::SeekStyle::*;' at the top of libstd/io/mod.rs. E.g. try

    RUST_LOG=main=debug racer complete std::io::

    I'll try to fix this tonight

    Hmm.. It's a bit more tricky than I was hoping because you can have things like.

    #![feature(globs)]
pub use self::mod1::*;
pub use self::mod2::*;
pub use self::MyEnum::*;

pub mod mod1 {
    pub mod mod2 {
        pub enum MyEnum {
            V1,
            V2
        }
    }
}

fn main() {
    let v = V1;    // this is legit!
}

    I think racer will need to do memoization and then abort on a recursive glob path. Am not going to get this finished tonight unfortunately

    Have added a notice to the front page. I've gone down with some sort of flu bug so I'm not going to get this done today either, sorry!

    Thanks kiljacken!
    I've think I've fixed this now. Does it work on windows?

    It does indeed seem fixed!

    Thanks or your hard work.
