There is no memory leak on my computer. I used Version 3.0 on Windows 2000.

Hi all,

I've discovered another memory leak in Mathematica. When I execute the
following code:

In[6]:=
Do[Print[MemoryInUse[]]; ListConvolve[{1, 2, 3},
    {2, 3, 4}], {10}]

1255008
1255144
1255168
1255192
1255216
1255240
1255264
1255288
1255312
1255336

You can see that each loop has an increase in the memory usage for no
apparent reason. This memory leak occurs with version 4.0 under WindowsNT.
It does not occur with version 4.1 under Linux. I would appreciate it if
anyone out there with a different configuration than the above would check
out whether a memory leak exists for their configuration.
