[Bug c/27233] New: incorrect xor result on arrays

[raphael dot ribas at gmail dot com]

the following code

#include <stdio.h>

int main() {
    int a[1],b[1];
    a[0]=5;
    b[0]=7;
    a[0]^=b[0]^=a[0]^=b[0];
    printf("%d %d\n",a[0],b[0]);
    return 0;
}

this should produce "7 5" as outpout but it produces "0 5"
