[LLVMdev] Creating a global variable in JIT context

I'm trying to create a global variable initialized to zero, and return
its value from a newly created function, in JIT context. I'm keeping
all types as i32 for the moment, and I only have the one module

This is the code I have for creating the global variable:

	const Type *type = Type::getInt32Ty(getGlobalContext());
//	Constant *zerov = Constant::getNullValue(type);
	Constant *zerov = Constant::getIntegerValue(type, APInt(32, 0));
	V = new GlobalVariable(getGlobalContext(), type, 0,
GlobalValue::PrivateLinkage, zerov, name);

And these are the error messages given by verifyFunction:

Function return type does not match operand type of return inst!
  ret i32* @x i32Referencing global in another module!
  ret i32* @xBroken module found, compilation aborted!

Any idea of what I might be doing wrong? Is this the right way to be
going about it in the first place?
