Then in the Coroutine Body of C, it would try to switch to itself by symmetric transfer. However, the Coroutine frame of C now is a stack variable. Then the tail call would pass the address of the stack variable whose lifetime has ended, so here is the corruption. Did I understand the situation?

Yes I believe that's an accurate description
