--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Actually the bug is in the testcase as it aggregate-copies
struct sockaddr_storage
{
sa_family_t ss_family;
unsigned long int __ss_align;
char __ss_padding[(128 - (2 * sizeof (unsigned long int)))];
};
where by C rules an aggregate copy copies each field and thus leaves padding
undefined.
Thus this is a libc bug of having padding between ss_family and __ss_align.
And thus this has nothing to do with strict aliasing. It's rather a glibc
bug (or specification bug wherever sockaddr_storage is specified).
