--------------------------------------
Hi Namit,
I was able to reproduce this issue so far on my setup. However, I wasn't
sure on how to reproduce this issue on using tables in unit-tests. I can
provide an updated patch with your test right away. I am still actively
working on this issue.
Thanks
Vikram.
