Thanks! I re-tested my reproducer with the latest Emacs and the error is
gone. I was not able to trigger crashes either.
Feel free to close this bug.

I am currently playing with an alternative approach.
Simply caching recent avl-tree queries into a short vector can improve
the search time nearly 2x (according to real-usage statistics).
The idea is described in
Pugh [Information Processing Letters] (1990) Slow optimally balanced
search strategies vs. cached fast uniformly balanced search strategies.
