Could you help me why this memcpy cause hardfault?

I added ams service to my project, and I tested with my iphone 7P, seems all goes well. But today I tested with my iphone 5S, sometimes the hardfault exception raise.

Hi,

I think it would be interesting to compare the input arguments to memcpy when you get the hardfault and when it works. Maybe the size argument is too big, hence causing memcpy to overwrite data outside of  "remote_command_list" variable
