Hmm.. Looks like A3 pointing to seglist is just a randomly chosen temp register used as a jump address and application imho shouldn't assume it containing anything useful.
Contents of A2, A5 and A6 and others are side-effect of BCPL calling convention and they need to be exactly correct but A3 is more or less a BCPL scratch register.
Anyway, it can be "fixed"..
