I'd start with checking what NVCC generates for the initializers. Considering 
that ultimately we need to conform to CUDA runtime expectations and given lack 
of documentation, NVCC-generated code is the only reference we have.
Compile your example with -keep and see what NVCC-generated registration code 
looks like.
