This is most likely a dup of bug 26197.

------- Comment #4 from pinskia at gcc dot gnu dot org 2006-03-02 04:12 -------
Reduced testcase:
struct fd_set {
char fds_bits[1024];
};
void joy_polldev(char *a)
{
struct fd_set readfds;
unsigned int __i;
for (__i = 0;__i < 1024;++__i)
readfds.fds_bits[__i] = 0;
f(&readfds, *a);
}

Compile with -O2 -ftree-vectorize -msse2 --param max-aliased-vops=0 to see the
problem. the --param max-aliased-vops=0 is required, otherwise we don't get
the aliasing groupings.

Yes this is the same bug as PR 26197. Closing as a dup.
