Hi Brian,

The issue here is that "NewExecutionEngine" will create either an MCJIT- or
an interpreter-based execution engine, and only the former will be able to
resolve symbols in the parent process. MCJIT will only be used if you have
called the appropriate initialisation functions first. If you add the
following to the top of your main() function, it should work:

LinkInMCJIT() InitializeNativeTarget() InitializeNativeAsmPrinter()

Cheers,
Andrew
