Hello,
I'm running the gcc 6.3.0 version with opensource code in ubuntu 16.04 LTS.
When I run my code, I am getting error.

According to the code,
https://github.com/OpenNetworkingFoundation/libfluid_msg/blob/master/fluid/ofcommon/common.hh
(line 28).
It is destrucutor call. I guess it should delete automatically.
My question is that why I am getting this strange reasons?
Thanks For your help.
Best regards
