(Get the code!)
The existence of code written by people who should never have been allowed to touch a keyboard cannot be allowed to prevent a correct implementation. If there is a large bod of code out there we can work around the issue for that.
We can have the existing memcpy@GLIBC_2.2.5 implementation work around the issue by avoiding the backward copying code. A new memcpy@GLIBC_2.14 could use the code currently in use.
Whether the current, new memcpy is only slightly faster than one mimicking memmove is really not that important. There are going to be more and different implementations in the future and they shouldn't be prevented from being used because of buggy programs. We should be happy to have this code here and now.
With this proposed implementation old code remains in working order until those lousy programmers use a newer platform and then they will experience the problems themselves and will fix them before releasing their code.
I'm happy to entertain a patch to this effect.
