64-bit lli can't run 32-bit bitcode?

Hello,

I am trying to run 32-bit bitcode with lli built with 64bit configuration.
But it always crashes without any messages when I try to run 32bit bitcode.
If anyone experienced same situation and have some clues to resolve, can you please share?

FYI, I am using lli in llvm-3.0

Thanks,
Taemin
