Error: call depth limit reached in a debug build (600 function calls). You can change it with -d:nimCallDepthLimit=<int> but really try to avoid deep recursions instead.

The destructor of rope is called recursively and excess the maximum call depth.

Now it is no longer crash after #20433 was merged but it is much slower in compilation speed than refc booting compiler.
