Bug#85468: [PR target/9082] [alpha] memcpy makes unaligned access

[Falk Hueffner <falk.hueffner@student.uni-tuebingen.de>]

Hi,

looking at the preprocessed source clearly reveals that this is not a
gcc bug:

union {
    struct id_ts {
	n_time its_otime;
	n_time its_rtime;
	n_time its_ttime;
    } id_ts;
    struct id_ip {
	struct ip idi_ip;
    } id_ip;
    u_long id_mask;
    char id_data[1];
} icmp_dun;
[...]

icp = ( struct icmp* )( buffer + hlen );
[...]
memcpy( &sent_time, icp->icmp_dun.id_data + ((size_t) &((PING_DATA *)0)->ping_ts), sizeof( sent_time ) );
memcpy( &this_count, icp->icmp_dun.id_data, sizeof( this_count ) );

id_data is 8-byte aligned. offsetof ping_ts is 8. So gcc rightfully
concludes the source is 8-byte aligned. Aparently, the cast from
buffer + hlen is bad.

Please reassign this bug to fping.
