It isn't the same issue. The submitter of #3506 claimed the code
that GCC currently generates is incorrect, which obviously is not
the case. _This_ PR on the other hand merely asks for GCC to
be enhanced to generate _better_ code for this; a wholly different
thing. So do not close as a duplicate again, thank you.
