27 /* alloca (N) returns a pointer to N bytes of memory
28  allocated on the stack, which will last until the function returns.
29  Use of alloca should be avoided:
30  - inside arguments of function calls - undefined behaviour,
31  - in inline functions - the allocation may actually last until the
32  calling function returns,
33  - for huge N (say, N >= 65536) - you never know how large (or small)
34  the stack is, and when the stack cannot fulfill the memory allocation
35  request, the program just crashes.
