freeobject and proxies


    Feb 14 2006 | 4:43 am
    hi, i'm having the trouble of max crashing whenever i unload my external,
    i think it is an issue of me incorrectly attempting to free some proxies.
    am i unclear on the syntax or is there something i'm overlooking? any
    help would be appreciated. - dan
    (also i notice that there is now a development forum, is it inappropriate
    to ask these kinds of questions over the main list?)
    code examples
    ----
    here i predeclare them:
    typedef struct _comb{
    t_pxobject x_obj;
    void *t_proxy[4];
    float *data;
    float *data2;
    long InletNum;
    long index;
    long index2;
    long allocsize;
    long size;
    float A;
    float B;
    float C;
    long Delay;
    long samperms;
    } t_comb;
    ...
    then i reference a free routine in main:
    void main (void)
    {
    setup((t_messlist**)&comb_class, (method)create_object,
    (method)destroy_object, (short)sizeof(t_comb), NULL, A_DEFLONG,
    A_NOTHING);
    ...
    i declare them as inlets:
    void *create_object(long maxsize)
    {
    t_comb *mo = (t_comb*)newobject(comb_class);
    mo->t_proxy[3] = proxy_new(mo, 4, &mo->InletNum);
    mo->t_proxy[2] = proxy_new(mo, 3, &mo->InletNum);
    mo->t_proxy[1] = proxy_new(mo, 2, &mo->InletNum);
    mo->t_proxy[0] = proxy_new(mo, 1, &mo->InletNum);
    ...
    and later attempt to free them:
    void destroy_object(t_comb *mo)
    {
    free(mo->data);
    free(mo->data2);
    freeobject(mo->t_proxy[4]);
    mo->data = mo->data2 = NULL;
    mo->allocsize = mo->size = mo->index = mo-> index2 = 0;
    dsp_free(&(mo->x_obj));
    }

      You are freeing a piece of memory you don't own.
      freeobject(mo->t_proxy[0]);
      freeobject(mo->t_proxy[1]);
      freeobject(mo->t_proxy[2]);
      freeobject(mo->t_proxy[3]);

      Ah, this is good to realize, unfortunately i have tried this and also tried it again just now, but the external continues to give me this same problem. What else could i be doing wrong?
