Yes, the funny cast is *intended* to alias all memory, and thus force anything
that might potentially alias the string to be written back. We don't have the
ability to conclude that __d3 won't be affected.
As for <bits/string.h>, the version in current glibc seems to be very different
and should not exhibit the problem shown here.
