Yes you are right. The bug was fixed in main trunk of apache but not in 2.2.x branch. memcpy-ssse3 has code for forward and reverse copy. Why?
However, I suggest you add a debug statement to memcpy, to monitor overlapping calls, whether it's just the isolated case.
Maybe some developers quietly ignore the note about overlapping in memcpy and then they are surprises.
