Well, a *complete* self-contained example would help. Not some
snippets taken out of context. Simply by the process of reducing
it to that, one often finds the problem.
Returning a NULL pointer is fine, as well as printing it (it'll
print as: cdata<...>: NULL).
Also, build LuaJIT with debug symbols enabled, otherwise the
debugger output isn't very useful.
