// Q: What are the 'a'-variant allocation functions?
// A: They allocate memory from the stack, which is automatically 
//    freed when the invoking function returns.
//    But it's not portable (http://c-faq.com/malloc/alloca.html)
//    and I have doubts our implementation works.
//    -> They should NOT be used, period.
