I spend some more time reading the code. It seems that the member `vts` of struct `BalloonEval` needs to be initialized in `check_due_timer()` after allocating the storage. Otherwise the pointer `vts` has arbitrary value and `vim_free()` is called in `get_beval_info()` for this uninitialized pointer.
The attached patch solves the problem for me. I don`t know if this is the best solution.
