[Insight-developers] Invalid read in ConnectedComponentImageFilter

[Bill Lorensen]

Gaetan,

In ConnectedComponentImageFilter, valgrind is giving an
UMR ==8366== Invalid read of size 1
at
itkConnectedComponentImageFilter.txx:132
It seems that inLineIt is being incremented after the IsAtEndOfLine(),
causing the invalid read.

   127 :


 while ((PVal != NumericTraits<InputPixelType>::Zero) &&
 128 :


 (! inLineIt.IsAtEndOfLine()))
 129 :


 {
 130 :


 ++length;
 131 :


 ++inLineIt;
 132 :


 PVal = inLineIt.Get();
 133 :


 }
 134

Can you take a look at this?

Thanks,

Bill
