- * FIX : src/gdcmDocument.cxx Remove obvious code in the destructor
+ * FIX : now, the DocEntries are all deleted in the gdcmElementSet.
+ Two problems appear when doing it :
+ - with the gdcmFile : when the GetImageData method is called, the pixels
+ are stored in the gdcmPixelConvert, but a gdcmBinEntry link to these
+ datas (pixels). And each structure destruct the datas when it's
+ destructed. So we have two destructions for the same datas. To solve it,
+ a flag is added in the gdcmBinEntry to indicate if the BinEntry owns the
+ datas or not. If it doesn't own datas, then they will not destroyed by
+ the gdcmBinEntry.
+ - with the gdcmDicomDir : the sequences (gdcmSQItem) contain DocEntry
+ elements. The DicomDir* (DicomDirPatient, etc.) inherit from SQItem.
+ Thus destruct the DicomDir* elements and the TagHT of the ElementSet
+ create a double destruction of the same DocEntry's. So, to solve it,
+ the TagHT is simply cleared and the DicomDir* elements are destroyed.
+ * TODO : add an entry concerning memory leaks in the DicomDir

* FIX : src/gdcmPixelConvert : Set to NULL the deleted structures in the
squeeze method

+Description: gdcmDicomDir and SQItem creation
+Date: 2004 Nov 16
+Attributed:
+Details: DicomDir creates some SQItem (by new). After that, it creates
+ the corresponding DicomDirPatient, etc. using the content of the SQItem
+ (the content is composed with some DocEntry's that can't be destroyed).
+ So, if the SQItem is deleted, then it's content is deleted to. But the
+ DicomDirPatient, etc. use the content of the SQItem. Then, the SQItem can't
+ be deleted, and when have memory leaks
+
-----------------------------------------------------------------------------
Description: [BUG] Better handling of unfound Dicom dictionary.
When gdcm doesn't find the Dicom dictionary (because it's
a.write(output);
