An instruction which is using indirect dec / indirect inc addressing that runs in an address / bus error doesn't change the addressing register. (valid for 68000 only ... I think)

What is happening for instructions with multiple indirect dec / indirect inc addressing operations, like abcd or movem
Assume following instruction causes a bus error by reading the second operand. What value contains the register A1 afterwards?

ABCD -(A1), -(A1) -> (A1 = 2)
