Does slen (set to l3len - hlen) come out correct? Given that it's
inlined htons, I'm assuming you compiled with a nontrivial -O level,
so it shouldn't be surprising either that it optimized out a local
variable or that the debug info gives you misleading results which may
or may not reflect what's actually happening.
