Eric --
Sorry -- my idea about fixing this in the front end is bogus. It's OK to
dereference a pointer-to-member to a virtual function member even if the base
class doesn't have any virtual functions; c.f., g++.old-deja/g++.martin/pmf1.C.
So, I've unassigned myself; you'll have to look for a solution in the back end.
I don't understand your Comment #12 regarding MEM_NO_TRAP_P; MEM_NO_TRAP_P
calls rtx_addr_can_trap_p. I'd suspect that making rtx_addr_can_trap_p respect
STRICT_ALIGNMENT (by checking the values of the CONST_INT added to the
non-trapping address) would work.
