Ok, I took a look.  Its hard for me to tell much from your report. I 
don't have Visual Studios (or Windows for that matter) and can't easily 
reproduce.

It would really help to know if this is a problem with the C bindings or 
the generated IR.  If you manually create the expected IR and run it 
through opt/llc, does that work?

Can you include the full output of this example?  Both the IR and the 
error would be useful to see.

One observation, it looks like you're using the erlang GC not shadow 
stack?  e.g.
LLVM.SetGC(sum, "erlang");
