          So it does appear to be related to the memcpy change in libc.

        
        So eCryptfs is buggy, just fix it.
The compatibility stuff that has been added to glibc to workaround
buggy old programs was just for programs linked against old glibc.
If you compile it again and you want it still working, fix it.
It isn't that hard.

      
      I'll try tomorrow, I hope it is obvious bug.


    memove should be used if areas overlap that are being copied.
