[ITK] [ITK-users] ImageSeriesReader type pointer crashes in debug mode

[Ritesh Mahajan]

Thanks for reply. I shared the same issue with forum as well under community category. Please find the below code. This is simple cpp file containing function to read dicom. In which the dicomReader pointer is made global. This code runs in release mode and crahes in debug mode. While debugging i found that i crashes in itkImageSource class under template< typename TOutputImage > ImageSource< TOutputImage >::ImageSource(). 

// itk headers 
#include "itkGDCMImageIO.h" 
#include "itkGDCMSeriesFileNames.h" 
#include "itkImageSeriesReader.h" 
#include "itkImageSeriesWriter.h" 
#include "itksys/SystemTools.hxx" 
#include "itkVersion.h" 
#include "itkImage.h" 
#include "gdcmUIDGenerator.h" 
#include "itkFileOutputWindow.h" 
#include "DicomReader.hpp" 

using namespace std; 

typedef signed short PixelType; 
typedef itk::Image< PixelType, 3> ImageType; 
typedef itk::ImageSeriesReader< ImageType > ReaderType; 
typedef itk::GDCMImageIO ImageIOType; 
typedef itk::GDCMSeriesFileNames NamesGeneratorType; 

ReaderType::Pointer dicomReader= ReaderType::New(); 

void ParseDicom(const string &dicomDirectory) 
{ 
NamesGeneratorType::Pointer apNamesGenerator = NamesGeneratorType::New(); 
ImageIOType::Pointer apGdcmIO = ImageIOType::New(); 

apNamesGenerator->SetInputDirectory(dicomDirectory); 

const ReaderType::FileNamesContainer & filenames = 
apNamesGenerator->GetInputFileNames(); 

dicomReader ->SetImageIO(apGdcmIO); 
dicomReader ->SetFileNames(filenames); 
try 
{ 
dicomReader ->Update(); 
} 
catch (itk::ExceptionObject &excp) 
{ 
std::cerr << "exception in file reader " << std::endl; 
throw (excp); 
} 
}

Hi Ritesh, 

When code crashes in Debug mode, but runs in Release or vice versa, it means it has a deficiency (bug) which manifests in one of those modes. As you did not provide the code which uses the reader, I cannot offer any more specific advice. Providing a runnable example will make it easier for people to help you. 

We have transitioned away from this list, to the forum . Please post your updated question there, as more people will see it. 

Regards, 
Dženan

Hello Team, 

When i am creating a smart pointer globally and allocating the memory to it. 
In debug mode "it crashes". While when the same code is run in release mode 
it seems to work fine. Can some one help me out why is it so ? 

Please find the below code: 

typedef signed short PixelType; 
typedef itk::Image< PixelType, 3>ImageType; 
typedef itk::ImageSeriesReader< ImageType >ReaderType; 
ReaderType:: Pointer reader= ReaderType::New(); 

void ImageRead() 
{ 
// using pointer reader here. 
// which is allocated memory at global level 
} 

The above code crashes in debug mode
