As I said, I don't think this is supposed to be a problem. I actually
do this all the time in my own code.

So again, in your C/C++ code, what happens if you call
printf("Hello);? Does it also hang?

What if you completely remove your current script and replace it with
a single line of code?
print("Hello")
What happens if you replace this single line of code with:
foo = 1+1
(so there are no I/O calls)

What if you create your own new C print function and register it with
your lua script and use that instead? (Typed in mail so beware)
/* Crappy print that only prints one string */
static int my_print(lua_State* L)
{
  printf("%s\n", lua_tostring(L, -1);
  return 0;
}

// Somewhere in your setup code
lua_pushcfunction(ls, my_print);
lua_setglobal(ls, "myprint");

-- In Lua code
print = myprint;  -- override the default print if you want
myprint("hello")
