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.
