bitcode for test case

I'm using LLVM 2.0 on Linux/x86. With the attached bitcode file, I get:

foad at debian:~$ ~/svn/antix/agp/trunk/toolchain/install/bin/opt -f -o opt.o
20050316-1.bc -lower-packed
Unhandled Instruction with Packed ReturnType:   %tmp3 = bitcast i64 %tmp12 to
<2 x i32>         ; <<2 x i32>> [#uses=1]

std::vector<llvm::Value*, std::allocator<llvm::Value*>
>&<unnamed>::LowerPacked::getValues(llvm::Value*): Assertion `false &&
"Unhandled VectorType value"' failed.
