Regarding not using alloca() within function parameters, see the
BUGS section of the alloca(3) man page.

+- Use memzero() or even better zero() instead of memset(..., 0, ...)

+- Instead of using memzero()/memset() to initialize structs allocated
+ on the stack, please try to use c99 structure initializers. It's
+ short, prettier and actually even faster at execution. Hence:
+
+ struct foobar t = {
+ .foo = 7,
+ .bar = "bazz",
+ };
+
+ instead of:
+
+ struct foobar t;
+ zero(t);
+ t.foo = 7;
+ t.bar = "bazz";
