Why does dicomread crash when reading certain DICOM CT Images?

I'm attempting to read anonymized CT image files into Matlab. Most of the files work, but there are a few which cause Matlab to crash. It's very reproducible.
I've tracked it to the dicomparse call in newDicomread, but can't debug it any further.
I've compared the attributes of this image to others and can find no unexpected difference in the files. The images are compressed Lossless JPEG. The original files were generated by a GE Scanner.
I'm running Matlab 2014a 64-bit on a Windows 7 box. If I start Matlab from a command line there is no output which would provide more information.
Any ideas as to what may be going wrong?
Thanks

Scott,
I have the same issue - but it cropped up when writing a utility to compress dicoms that contain fluoroscopic time series & testing it. I could dicomread the original dicoms but after saving them in a jpg2000 lossless compression format certain ones crash matlab upon reading them back in. Perhaps someone from matworks can help?
