[Pkg-rust-maintainers] Bug#808576: rustc cannot compile programs: "unrecognized relocation in section"

[Robbie Harwood]

Package: rustc
Version: 1.5.0+dfsg1-1
Severity: important

Dear Maintainer,

When I try to build any rust program, the following occurs:

$ cat > main.rs
fn main() {
  print!("Hello, world!\n");
  }
$ rustc main.rs
error: linking with `cc` failed: exit code: 1
