--- Comment #1 from Alexander Cherepanov <ch3root at openwall dot com> --- clang bug -- https://bugs.llvm.org/show_bug.cgi?id=44342 There is a second example there, with memcpy/memcmp, but it doesn't trigger the bug in gcc so not pasting it here. (Generally gcc seems to be much less consistent than clang in optimizing integers vs. memcpy/memcmp.)
