I had setup for TPCH scale factor 5, I could reproduce the hang
reported by you with Q10. I have fixed the issue in v10 (only 0003 is
changed other patches have no change). However, after fixing this
issue it's crashing in parallel shared hash patch and call stack is
same what you have reported on parallel shared hash thread[1]

Please verify with the new patch.
