I can reduce the code to

ListCorrelate[#1, #1, 1] & @ InverseFourier[Fourier[Table[0, {17}]]]

and it still crashes the second time. The length of the table should
be 17 or higher for the crash to occur.

Replacing InverseFourier[Fourier[Table[0, {17}]]] with their result if
evaluated on a separate line, i.e. with {0., 0., 0., 0., 0., 0., 0.,
0., 0., 0., 0., 0., 0., 0., 0., 0., 0.} does *not* lead to a crash.

ListConvolve leads to the same problems as ListCorrelate.

Looks like a clear internal Mathematica bug. It does this in 6 only.
Mathematica 5.2 works fine in this respect.

I suggest you report it to Wolfram Research.
