Incident note: 173928, 173957, 173998 and 174605 - P2SH redeem-script failure (2012)
Each body includes the same 123-byte transaction, 4005d6bea3a93fb72f006d23e2685b85069d270cb57d15f0c057ef2d5e3f78d2, which spends a pay-to-script-hash output funded at canonical 170054, b0539a45de13b3e0403909b8bd1a555b8cbe45fd4e3f3fda76f3a5f52835c29d:1, worth 400000 satoshis.
Its scriptSig pushes only the redeem script, a 1-of-1 OP_CHECKMULTISIG.
The pre-BIP16 template check hashes that push and compares it, and passes; executing the redeem script finds no signature on the stack and fails.
Nodes applying the 1 April 2012 rules rejected these blocks while older nodes accepted them, which is how the same transaction was included by many miners for months.
Core today reports block-script-verify-flag-failed (Operation not valid with the current stack size).
