It should be on top of the stack; if it's not there, something else has
gone wrong. If lua_pcall is succeeding, all I can think of offhand is
that you're calling it with nresults equal to 0, eg,
    lua_pcall(L, 0 /* nargs */, 0 /* nresults */, 0 /* handler */);
Which will discard all return values. Try calling it with 1 or
LUA_MULTRET instead:
    lua_pcall(L, 0, 1, 0);
And see the reference manual for more details.
If the call is succeeding and you're calling it with a >0 nresults and
it's still not putting anything on stack, I can't think of anything.
