What I would do is to take a simple existing plugin, like 
Matrix2x3Plugin, and generate the C from slang. Then I'd compare that C 
code with your hand written one. I guess the difference is there. 
Something else I'd try is to copy Matrix2x3Plugin with a new name, like 
TestM23Plugin, generate c, compile the library, and see that it works.
