In somelib.rc:

#[crate_type = "lib"];
#[link(name="somelib", vers="0.0")];
pub struct S<T>(Option<T>);
pub fn mk<T>() -> S<T> { S(None) }

In client.rs:

extern mod somelib;
fn main() { somelib::mk::<int>(); }

Do the following:

$ rustc somelib.rc
$ rustc -L. client.rs
error: internal compiler error: unexpected failure
note: the compiler hit an unexpected failure path. this is a bug
note: try running with RUST_LOG=rustc=1,::rt::backtrace to get further details and report the results to github.com/mozilla/rust/issues

Notes:

  • Does not require Option. pub struct S<T>(~[T]) or pub struct S,T>(()) also
    cause ICEs.
  • Requires polymorphism; pub struct S(()) does not cause an ICE.

Backtrace follows:

Struct ctors appear to be totally unimplemented cross-crate. I'll take this on, shouldn't be hard.

This code now compiles just fine. Flagging as needstest.
