upcall fail 'ty_size: unhandled type' in src/rustc/middle/trans/native.rs

[flaviusb]

When compiling the sqlite bindings for rust from https://github.com/linuxfood/rustsqlite/ I hit the error
error: internal compiler error unexpected failure.

I am running on Rust HEAD (43751e4).

When I run
RUST_LOG=rustc=0,::rt::backtrace rustc sqlite.rc after cloning linuxfood's rustsqlite repo, I get this as output:

I went digging in src/rustc/middle/trans/native.rs, and the problem seems to be that fn ty_size(ty: TypeRef) -> uint is being called with a TypeRef of type FunctionTyID (which gives an integer 11 in the alt).

I am not sure where to go with this from here, and have not been able to put together a minimal test case.

This is fixed in current head.
