Summary0007594: Crash when writing the output of an " In Place" filter with the InPlace feature ON. Happens with TIFF images.
DescriptionThe program in the attached file crashes when the input is a *.tif image. The program does a simple thresholding "in place". I found out that the crash has nothing to do with filtering but with writing an output image in a file. Although, it's not possible to catch it as an exception - the error happens because a null pointer is addressed within one of the functions called inside TIFFImageIO::Read().

I've done a bit of debugging and that is what I've found. In a pipeline,
that connects a reader with a filter with a writer, calling
writer->Update() causes an update of a reader, because, with
filter->InPlaceOn(), the filter input gets released. For tif images,
TIFFImageIO::Read() is called, which uses m_InternalImage that is
supposed to have a non-null pointer m_Image to an allocated piece of
memory. m_InternalImage is filled in TIFFImageIO::CanReadFile(), which
is not called the second time, as a part of writer->Update() procedure.
As a result, m_InternalImage->m_Image points to NULL, and causes the
runtime error when addressed in TIFFImageIO::Read(). If one includes
filter->GetOutput()->DisconnectPipeline() before calling
writer->Update(), no error occurs because no input image update occurs.
TagsNo tags attached.

 I was unable to reproduce the behaviour with the provided example and latest CVS version (3.19). Checked in Win32 - VS2008 Express. TIFFImageIO::Read() is not called the second time.
