Confirmed. I do not know where this is coming from.
It looks like DOM:
<L3>:;
if (one_valid_2 == 0) goto <L4>; else goto <L6>;
<L4>:;
if (T.4_14 != 0) goto <L5>; else goto <L6>;
<L5>:;
# one_valid_1 = PHI <0(5), one_valid_2(4), 1(6)>;
See how the PHI has both 0 and one_valid_2 there when it should have two one_valid_2 and a 1.
