Bug 281828

Version:           3.6.0 (using KDE 4.7.1) 
OS:                Linux

#include <string.h>
#include <iostream>

int main()
{
  int a[4] = { 0, 1, 2, 3 };

  memmove( a, a+1, 2*sizeof(int) );
  
  std::cout << a[0];
  std::cout << a[1];
  std::cout << a[2];
  std::cout << a[3];

  return 0;
}

Results in:

==30707== Source and destination overlap in memcpy(0x7ff000080, 0x7ff000084, 8)
==30707==    at 0x4C27B46: memcpy (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
==30707==    by 0x400753: main (main.cpp:8)
