llvm dev - Apr 2012 - [LLVMdev] Demo invalid instruction

Using the LLVM demo <http://llvm.org/demo/> with this code:

>   S s;
>   s.throw_it();

and selecting C++ as the source language an "LLVM C++ API code" as the
target gets me:
> LLVM ERROR: Invalid instruction

Some exception-handling-related updates to the code that generates the
C++ output didn't make it into the 3.0 release.
