Unlike OP_IF and OP_NOTIF which interpret the top stack item as a number, OP_IFDUP interprets it as a boolean. This has important consequences because numbers are imited to int32s while booleans can be an arbitrary number of bytes. The offending script was found and reported by Jonas Nick through the use of fuzzing. |
