When I run this on my ubuntu 20.04 system, the line CTR_Mode< AES >::Encryption e; has an error tips segment fault.
Since this is the standard example, I don't know how to solve this error.
Moreover, this example runs well in Win 11.
So, is it blame to linux?
Please tell me how to fix this problem. Thank you.
I want to solve this bug, I don't want to change to Win 11 to run this code.
