You forgot to mention that this is only when you ask for the anonymous structs:
[acme@doppio object_samples]$ pahole --anon_include feng.pahole.crasher.20090508
<BIG SNIP>
typedef struct {
sock_type socktype; /* 0 4 */
int fd; /* 4 4 */
struct sockaddr_storage local_stg; /* 8 128 */
/* --- cacheline 2 boundary (128 bytes) was 8 bytes ago --- */
struct sockaddr_storage remote_stg; /* 136 128 */
/* --- cacheline 4 boundary (256 bytes) was 8 bytes ago --- */
struct sockaddr_storage multicast_stg; /* 264 128 */
/* --- cacheline 6 boundary (384 bytes) was 8 bytes ago --- */
sock_flags flags; /* 392 4 */
/* XXX 4 bytes hole, try to pack */
char * remote_host; /* 400 8 */
char * local_host; /* 408 8 */
in_port_t remote_port; /* 416 2 */
in_port_t local_port; /* 418 2 */
/* XXX 4 bytes hole, try to pack */
void * ssl; /* 424 8 */
void * data; /* 432 8 */
/* size: 440, cachelines: 7, members: 12 */
/* sum members: 432, holes: 2, sum holes: 8 */
/* last cacheline: 56 bytes */
} Sock;
Segmentation fault
[acme@doppio object_samples]$ pahole -Aa feng.pahole.crasher.20090508
Must be some bug I introduced in the last month or so, investigating.

Having.
