Hi everyone,

I'm using Mathematica 6.0.2 and the kernel crashes consistently when
evaluating the line:

Dot[SparseArray[{i_, i_} -> 1, {2, 2}], Table[Range[2], {2}]]

It's just a dot product of two matrices. Anyone else getting the same
problem in v.7? Maybe it's time for me to upgrade.

Thanks for the help,
Norbert

This works fine just as I would expect in version 7 with no crash

In[148]:= Dot[SparseArray[{i_, i_} -> 1, {2, 2}], Table[Range[2],
{2}]]

Out[148]= {{1, 2}, {1, 2}}

In[149]:= $Version

Out[149]= "7.0 for Microsoft Windows (32-bit) (February 18, 2009)"

Cheers -- Sjoerd

Hi Norbert,

No crash here (M7.0, WinXP 32):

In[1]:=
Dot[SparseArray[{i_, i_} -> 1, {2, 2}], Table[Range[2], {2}]]


Out[1]= {{1, 2}, {1, 2}}

Regards,
Leonid

On my Windows XP box it crashes 6.0.2, with 7.0.1 everything seems to be
o.k.
