So... if I initialize the pointers the first time they are used, maybe that 
will help. It makes sense that the _new routine would be causing the problem, 
since it crashes when I load the object (PD disappears...)
I'll try it!

I guess because you don't initialize the pointers the first time. Your 
maskxor_new has:
 
  SETFLOAT(&x->masking.maskr[0], 0);
  SETFLOAT(&x->masking.maskl[0], 0);
  SETFLOAT(&x->masking.maskxor[0], 0);
...but x->masking.maskr etc. don't yet point to anything, they were 
declared as:
t_atom *maskxor, *maskl, *maskr;
...but not given any value. If it doesn't crash right there it will do 
so when you try to free the pointers:
  if (x->masking.maskl) {
    freebytes(x->masking.maskl, x->lengthl * sizeof(t_atom));
    x->masking.maskl = 0;
    x->lengthl = 0;
  }
