As far as I’ve tested I’ve noted that the termination of a thread does not call the destructor of any classes that were created inside the function running the thread.
See the test code below and the output below that. I’d expect ~~Test to be printed there as well!
I’ve also tried using a pointer to the thread and delete that after terminating but I couldn’t get the destructor to be run. Does this mean that this is a memory leak? I.e. when I use a pointer and run the thread for a wile before terminating it and creating a new thread will leave all the stuff allocated inside the thread function in memory?
And how can I get the desired behaviour of calling the destructor being called?
