Ah no, because we have global pointers here, with potentially unknowable
aliasing, as Alexander said.

I understand that it can't optimize much, my major concern is that the pointer
version of the code is so much worse than the index version of the code.

dest/src might alias anything (even themselves), so the compiler can't really
optimize much.

This is gcc-mp-7 pre-built object from MacPorts.
Should have mentioned that.
