[PD] specific external problem

when trying to dynamically create a user-defined amount of audio inputs, i try the following code but it just seg faults.

static void *multi_source_convolution_tilde_new(t_floatarg f, char *argv[]) {

int i;

  	t_multi_source_convolution_tilde *x =

(t_multi_source_convolution_tilde *)pd_new(multi_source_convolution_tilde_class);

x->f_multi_source_convolution = f;

//additional signal and float inlets

inlet_new(&x->x_obj, &x->x_obj.ob_pd, gensym("float"), gensym("first")); inlet_new(&x->x_obj, &x->x_obj.ob_pd, gensym("float"), gensym("bound"));

for(i = 0; i <= atoi(argv[2]); i++) { inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); }

//two signal outlets for stereo outlet_new(&x->x_obj, &s_signal); outlet_new(&x->x_obj, &s_signal);

return (void *)x; }
