The following code, when executed on Linux, leads to a segmentation fault:

OFFile* imageFile = new OFFile;
DcmOutputFileStream* outStream = nullptr;
imageFile->fopen(currentFilename.c_str(), "wb");
outStream = new DcmOutputFileStream(imageFile->file());
delete outStream;
delete imageFile;

The reason is that the ''FILE *'' handle is closed twice, once in the OFFile destructor and once in the DcmOutputFileStream destructor. This apparently works on Windows but crashes on Linux.

• add method in OFFile and/or DcmOutputFileStream that sets the ''FILE *'' to NULL without calling fclose()
• permit an OFFile instance to be passed to DcmOutputFileStream by reference
• add a flag in the constructor in both classes indicating whether or not the file descriptor should be closed in the destructor
