Volker Hilsheimer 204b6c9908 Fix out-of-bounds access when searching arrays 
Reported by Coverity.

All arrays in this code have the size Num... - 1, so accessing the entry
at Num... - 1 is out of bounds. Since we don't dereference the value,
and only use the address of the entry "one past the last" like an end-
iterator, this does not actually access out-of-bounds memory. However,
this code does rely on undefined behavior.

Use pointer arithmetics instead to get the address of the entry "one
past the last", which is well defined behavior and should satisfy
Coverity.
