One of my "favourite"s:

	for (x = 0; x < strlen(s); x ++)

(when the string is not actually mutated inside the loop).  In a few
cases a really good compiler might be able to prove s is not mutated
and hoist the strlen, but in most cases I've seen the loop is too
complex (calls out to externally-compiled functions, just plain too
big, mutates the string but happens to never do so in ways that change
its strlen, whatever).
