Hello,

I am getting a strange core dump, and was hoping that someone could shed
some light about what is going on.

The debugger seems to think that the seg fault occurs at line 91 of
itkDiscreteGaussianImageFilter.txx.

I was playing with the Canny parameters to see how they affected
differennt outputs by using a shotgun approach to looking at the parameters:

for var in 0.25 0.5 0.75 1.0 1.5 2.0 5.0 10.0; do
       for maxerror  in 0.001 0.01 0.1 1.0 10.0; do
          time ./itkCannyImageFilter
~/src/regressiontest/SGI/MR/5x-B2/TEST/10_ACPC/14831300_10_segment.hdr
test_${var}_${maxerror}.hdr $var $maxerror; echo "Done with $var
$maxerror";
       done ;
done

I thought it was very strange that max errors of .1 and 1 always causes
errors but the other values did not.

Please let me know if I am doing something wrong.

Regards,
Hans
