The below code snippet generates an internal compiler error, apparently related to the static vector declared inside the function.

#[link(name = "xml", vers = "0.1")];
#[ crate_type = "lib" ];
pub struct Parser<T>;
impl<T: std::iterator::Iterator<char>> Parser<T> {
    fn in_doctype(&mut self) {
        static DOCTYPEPattern: [char, ..6] = ['O', 'C', 'T', 'Y', 'P', 'E'];
    }
}

Still reproduces:

struct Foo;
impl<T> Foo {
    pub fn foo(&self) {
        static X: uint = 1;
    }
}
$ rustc 8134.rs
warning: missing crate link meta `name`, using `8134` as default
warning: missing crate link meta `vers`, using `0.0` as default
error: internal compiler error: encode_symbol: id not found 11

It appears to be an interaction with the generic; removing the <T> makes it compile fine.

f10e50a 
Whenever a generic function was encountered, only the top-level items were
recursed upon, even though the function could contain items inside blocks or
nested inside of other expressions. This fixes the existing code from traversing
just the top level items to using a Visitor to deeply recurse and find any items
which need to be translated.

This was uncovered when building code with --lib, because the encode_symbol
function would panic once it found that an item hadn't been translated.
