I'm not sure I've passed an invalid value; I've changed my code to not
delete the engine builder and it works:
auto ebuild = new llvm::EngineBuilder(
llvm::ExecutionEngine * ee = ebuild->
setErrorStr( &errStr ).
setEngineKind( llvm::EngineKind::JIT ).
setTargetOptions( topts ).
My code then runs fine. This is pointing towards destruction of the
`EngineBuilder` itself causing the problem (like it's deleting the
module although it shouldn't, since it's been given to the created
Leaf - the language we always wanted
