Thank you so much for your information. Our plan is to use it but with all means of test. We will look into the patch that you showed to us and decide if we can add it in our project.

Well, it is a non-trvial aggressive optimization.
Lately I planned to mark it finally as stable but then this happened popped up.
On the other hand, if only very few people are using it, we won't find remaining subtle bugs.
