The value it leaves on the stack depends on the last element on the stack. However, we can't make sure this element is OP_1 (which would give us the 'u' property) without the MINIMALIF rule. MINIMALIF is only policy for P2WSH, therefore giving 'd:' the 'u' property breaks consensus soundness: it makes it possible (by consensus but not policy) for instance to satisfy a thresh() without satisfying at least k of its subs. This bug was found and reported by Andrew Poelstra. |
