SDUse::setInitial should initialize List to null in your patch. You're
probably seeing random uninitialized data noise without that.
(Though valgrind wouldn't notice this because of the aggressive reuse
of allocated memory.)
Also, the replacement getOperandNo is returning the index in the
use list, rather than the index in the operand array.
