Created attachment 96350 [details] dhat log cannot start dhat program, the attachement is log . but when i upgrade valgrind to 3.11, the problem is not came out. Now, i use valgrind 3.11. So, it's ok for me. Maybe the log is helpful to develper.
No bug fix is done on 3.8.0 which is very old. I understand that this is working in 3.11.0, so closing as WONTFIX.
