Re: Would also bork legitimate code
Back in the days of the 8-bit processor, I remember writing code (in assembler!) that would implement a 16-bit jump by pushing the target onto the stack and doing a ret. Not all processors needed it, the 8080/Z80 has a JP (HL) instruction so that one didn't need to involve the stack, although it also had the EX (SP),HL instruction to make it easy to manipulate the stack content.
