Try something like:
unsigned char **msg_aux;
*msg_aux=(unsigned char *) malloc (8194); /*enough size...*/
i=i2d_PKCS7(p7,&msg_aux);
Or, if you do want to know the size before allocating:
unsigned char **msg_aux;
int sz;
sz = i2d_PKCS7(p7,NULL);
*msg_aux=(unsigned char *) malloc (sz); /*enough size! */
i=i2d_PKCS7(p7,&msg_aux);
