This isn't a bug.  The following line restores the interrupt

>         out __SREG__,__tmp_reg__

The interrupts are disabled only for the two cycles needed to
update the stack pointer.  If you took an interrupt with the
stack pointer half updated bad things happen!  I know.  I had
that bug in my RTOS for a while :)
