When a BSUN exception occurs, a preinstruction exception is
taken. If the exception handler returns without modifying the im-
age of the program counter on the stack frame (to point to the
instruction following the FScc), then it must clear the cause of
the exception (by clearing the NAN bit or disabling the BSUN
trap) or the exception occurs again immediately upon return to
the routine that caused the exception.
