lljit | Minimal Cython interface to LLVM JIT

I am trying to access a variable in the host program from LLVM IR, with a global variable, but I am having problems getting it to work. I am declaring a symbol with the required variable address in the main JitDylib. After that I create the Global variable with the same name, with external linkage so the linker can find it. But it does not work. Executing the Jit'ed functions crashes the host program.

Below is my test program based on the LLJIT example in the LLVM repository. I have tried many things such as using CreateGEP to get a valid pointer, or using a different JitDylib to declare the symbol. But none have worked for me. I suspect it is something linking related. Has anyone gotten it work using the new ORC V2 JIT API?
