Please file a PR. I don't have access to an ILP32 run-time environment, so I'm not sure how I'll be able to check this out. There are some pointer checks in the code so it's possible something is going awry. Can you compare the assembly output for ILP32 and LP64 to see if there's anything obvious? R.
