In contrast to PR 25937, I can reproduce this bug also on
x86_64-unknown-linux-gnu.

Shorter testcase:

=========================================
int foo(int *p, int n)
{
    int i, j, k = 0;

    for ( i = 0; i < 2; ++i, p += n )
        for ( j = 0; j < 2; ++j )
            k += p[j];
    return k;
}
=========================================
