Internal compiler error: cannot relate bound region. #14182
Description
The following minimal program reproducing the bug (in which I'm doing something terribly wrong I guess(?)):
fn main() {
let mut x: Vec< <'a> ||:'a> = Vec::new();
x.push(|| {});
}outputs the following error on when simply compiling on Windows 7 (64 bits, using the 32-bits binaries on the website to compile) with rustc minimal.rs:
minimal.rs:3:9: 3:14 error: internal compiler error: cannot relate bound region: ReLateBound(11, BrNamed(syntax::ast::DefId{krate: 0u32, node: 13u32}, a)) <= ReInfer(7)
minimal.rs:3 x.push(|| {});
^~~~~
note: the compiler hit an unexpected failure path. this is a bug.
note: we would appreciate a bug report: http://static.rust-lang.org/doc/master/complement-bugreport.html
note: run with `RUST_BACKTRACE=1` for a backtrace
