Thanks for trying this out!

Yes, there's a bug in the LLVM shipped with Mac OS X / XCode these days:
It contains a buggy prerelease of LLVM.  I haven't found a way to work
around it in Scheme 48, and it really does not seem worth it: I
downloaded the clang+llvm binaries from the LLVM site, and those work
just fine.
