This sort of thing isn't all that uncommon. The old 6800 had what we used to call the HCF opcode, "Halt and Catch Fire". When a program got lost in hyperspace it would inevitably hit either a Halt or this undocumented feature, at which point the address lines became a binary counter and the machine required a power reset to get it back.
I wouldn't be surprised at all to find accidental or QA opdcodes hidden away in other processors.
