<pre>Came across that with a fresh GCC trunk (towards GCC 9) build now, too. Looks
like a legitimate warning to me, as it appears that cnt - 1 == i can be true.
However, with a patch of "if (cnt - 1 != i)" around that memcpy, GCC still
emits the warning, for which I now filed
<<a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86196">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86196</a>> "Bogus -Wrestrict on
memcpy".</pre>
