@CosmikDebris Currently it is the case that OP_RETURN immediately marks the transaction invalid, but the the bug under discussion is exactly that its semantics used to simply be "stop execution" (which only resulted in failure if there was a false on top of the stack at that point). The practice of using OP_RETURN for burning funds came only years after this bug was fixed.

Thanks! I was under the impression that RETURN always implied the execution failed, since it is typically used to burn BTC. Is that what you meant by "fixing the RETURN operand"?
