Just inlining the example and error:

fn foo() -> Vec<usize>> {
    //                ^
    // error: expected one of `(`, `+`, `::`, `<`, `>`, `where`, or `{`, found `>`
    Vec::new()
}

Auto merge of #31455 - tmiasko:expected-tokens, r=alexcrichton
5d771cd 
Previously when breaking tokens into smaller pieces, the replace_token
function have been used. It replaced current token and updated span
information, but it did not clear the list of expected tokens, neither
did it update remaining info about last token. This could lead to
incorrect error message, like one described in the issue #24780:

    expected one of ... `>` ...  found `>`

This issue has been resolved after #31455 got merged.

rustc 1.8.0-nightly (3f4227af1 2016-02-10)

The error now is the following:

tmp/24780.rs:1:23: 1:24 error: expected one of `!`, `::`, `where`, or `{`, found `>`
tmp/24780.rs:1 fn foo() -> Vec<usize>> {
                                     ^
error: aborting due to previous error
