goto is just a tool and not to blame here. I don't know what you could call the root case of this one. Incomplete testing maybe? In Apple's case "goto" made it possible for the bug to occur, but there's no reason a different statement (or other typo) could cause equivalent damage. I think a common thread with both of these bugs is testing the failure cases, but to be fair to both validating software by finding bugs and/or validating functionality is affirming the consequent and you eventually need to ship.
