DicomImage::getInterData() and getOutputData() can return null when a corrupt DICOM's frame fails to decode, but their results were used without checking: getInterData() is immediately dereferenced via getData()/getRepresentation(), and getOutputData()'s pointer is stored and later memcpy'd in read_native_scanline(). The only guard was an OIIO_DASSERT, which compiles out in release builds, leaving a null-pointer dereference on malformed input. Check both and error cleanly.
