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