[Mp4-tech] Ex-Golomb words longer than 32 bits

[daljitsingh soc-soft.com]

Dear Experts,
Correct me if I am wrong. 
Question : For H.264 bitstreams, can Ex-Golumb codewords be longer than
32 bits?
Answer   : I think they can be.
Second question is, does JVT Reference Encoder function ue_v() support
writing of code words longer than 32 bits.
I am using JM code (JVT Reference code) with version 10.2 and it doesn't
support such code words.
I have been able to change reference code to support codewords longer
than 32 bits, however, JM Reference decoder fails to decode bitstreams
generated by modified code. 
Your comments, suggestions on this problem are solicited.
Thanks & Regards,
