Okay so I've delved a bit deeper, and run this program with lli
--force-interpreter and it gets this result:

   LLVM ERROR: Tried to execute an unknown external function: memcpy

I've read that one has to install libffi then re-configure and reinstall
llvm, however this hasn't worked for me. Perhaps I need to link it somehow,
but anyway.

I've also run the program with lli -debug and this is the end result:

********** EMITTING LIVE DEBUG VARIABLES **********

******** Post-regalloc Machine LICM: java/lang/Object::<init>() ********

SectionIdx: 7, Name: .shstrtab, Size: 54, Offset: 352, SectionData Size: 54
Segmentation fault

So this information doesn't really help or mean much to me. Any help is, of
course, much appreciated :)

Cheers,
Fraser
