LLVM assert with classes, regions and slices

[brson]

class CMap/& {
    let buf: [u8]/&;

    new(buf: [u8]/&) {
        self.buf = buf;
    }
}

fn main() { }

rustc: /home/banderson/Dev/rust2/src/llvm/lib/VMCore/Instructions.cpp:1056: void llvm::StoreInst::AssertOK(): Assertion `getOperand(0)->getType() == cast<PointerType>(getOperand(1)->getType())->getElementType() && "Ptr must be a pointer to Val type!"' failed.

Same assert with:

fn thing(x: &[int]) -> &[int] { x }
fn main() { }
