Summary:                    Crash with IAX2 incoming call: Bad magic number
Description: 
I' running Asterisk on MacMini G4 with OSX 10.5.1. 
It works very well with version 1.4.10
But since versions using astobj2.c file I have an error Bad magic number
when I receive a IAX call and Asterik quit.

I just test it with Asterisk 1.4.14 and it is the same.

Here is the function in astobj2.c wich get the error:

/*!
* \brief convert from a pointer _p to a user-defined object
*
* \return the pointer to the astobj2 structure
*/
static inline struct astobj2 *INTERNAL_OBJ(void *user_data)
{
struct astobj2 *p;

if (!user_data) {
ast_log(LOG_ERROR, "user_data is NULL\n");
return NULL;
}

p = (struct astobj2 *) ((char *) user_data - sizeof(*p));
if (AO2_MAGIC != (p->priv_data.magic) ) {
ast_log(LOG_ERROR, "bad magic number 0x%x for %p\n", p->priv_data.magic,
p);
p = NULL;
}

return p;
}
