this #define SHM_START_ADDR may be wrong

this define SHM_START_ADDR may overlap if one wants to use more dax0 bigger than 36GB!

You are correct. Thanks for pointing this problem. We will check the issue.
As a temporary solution, I would like to recommend change SHM_START_ADDR on your environment; there is no restriction of SHM_START_ADDR virtual address.
