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,

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)
mo->data = mo->data2 = NULL;
mo->allocsize = mo->size = mo->index = mo-> index2 = 0;

You are freeing a piece of memory you don’t own.

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?
