The slice does not know what other slices may be sharing the same
elements. So, increasing the length of a slice will relocate the
elements (almost always, with exceptions.) The following article goes
into a lot of detail:

Are you compiling as a 32-bit application? Then, chances are random bit
patterns look like references into these slices. (dmd uses a
conservative garbage collector). Try compiling with -m64.
