[Bug 609290] Re: overlapping memcpy in ssl_io_input_read

[Jiří Engelthaler]

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.
