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