[Insight-users] DicomSeriesReadPrintTags.cxx runtime error :"iterator not derefenceable"

[Árpád Szamosi]

I use 3.14.0, but I cleared the line return EXIT_FAILURE, because I
use that embedded in an vtkKWWidgets GUI .Sorry Im forgot that tell
you.
Anyway  if I paste "else" then "if" like:
if( tagItr == end )
    {
    std::cerr << "Tag " << entryId;
    std::cerr << " not found in the DICOM header" << std::endl;

    }
  else
	{
	  MetaDataStringType::ConstPointer entryvalue =
		dynamic_cast<const MetaDataStringType *>( tagItr->second.GetPointer() );

	  if( entryvalue )
		{
		std::string tagvalue = entryvalue->GetMetaDataObjectValue();
		std::cout << "Patient's Name (" << entryId <<  ") ";
		std::cout << " is: " << tagvalue << std::endl;
		}
	}
Look like works: If is there tag print that but if isnt the program to
continous.
