Hi, rustc fails to compile this program: ``` rust trait TheTrait { } struct TheStruct(~TheTrait); fn new() -> TheStruct { fail!() } fn main() { ~new(); } ``` with ``` $ rustc --version rustc 0.6 (a198aad 2013-06-13 03:25:11 -0700) host: i686-unknown-linux-gnu $ rustc usage.rs rustc: (path to my rust build)/src/llvm/include/llvm/IR/Instructions.h:704: llvm::Type* llvm::checkGEPType(llvm::Type*): Assertion `Ty && "Invalid GetElementPtrInst indices for type!"' failed. Aborted (core dumped) ```
