The original implementation sets $pc to the address read from the jump vector table first and links $ra with the address of the next instruction after the updated $pc. After jumping to the updated $pc and executing the next ret instruction, the program jumps to $ra, which is in the same function currently executing, which results in an infinite loop. This commit stores the jump address in a temporary, updates $ra with the current $pc, and copies the temporary to $pc.
