Thanks form the reply.
No, it's just an example. It's a big system so it's hard to present problem detailed.

For some reason, when object from struct is passed by reference to function and we want to manipulate by pointer on this object it cause BUS error.

With test function with param "struct _a *obj" (so pointer to struct is passed) works correctly.

Code:
int f3(struct _a *obj)
{	
printf("%llu", obj->_a2); <--- OK	
return 0;
}

Like I wrote, without optimization works correctly.

NAME
sip_init_conn_object, sip_clear_stale_data, sip_conn_destroyed - connection object related functions SYNOPSIS
cc [ flag ... ] file ... -lsip [ library ... ] #include <sip.h> int sip_init_conn_object(sip_conn_object_t obj); void sip_clear_stale_data(sip_conn_object_t obj); void sip_conn_destroyed(sip_conn_object_t obj); DESCRIPTION
The sip_init_conn_object() function initializes the connection object obj for use by the stack. The first member of the connection object (a void *) is used by the stack to store connection object specific stack-private data. The sip_clear_stale_data() function is used to clear any stack-private data in the connection object obj. The sip_conn_destroyed() function is used to intimate the stack of the pending destruction of the connection object obj. The stack clean up any stack-private data in obj and also removes obj from any caches the stack maintains. RETURN VALUES
The sip_init_conn_object() function returns 0 on success and the appropriate error value on failure. The value of errno is not changed by these calls in the event of an error. ATTRIBUTES
