patch 9.0.2115: crash when callback function aborts because of recursiveness Commit: https://github.com/vim/vim/commit/6701abfb522ec1d2ac18a04495ea874b94496ca6 Author: Christian Brabandt <cb@256bit.org> Date: Sun Nov 19 10:52:50 2023 +0100 patch 9.0.2115: crash when callback function aborts because of recursiveness Problem: crash when callback function aborts because of recursiveness Solution: correctly initialize rettv Initialize rettv in invoke_popup_callback() Since v9.0.2030, call_callback may exit early when the callback recurses too much. This meant that call_func, which would set rettv->v_type = VAR_UNKNOWN, was not being called. Without rettv->v_type being explicitly set, it still contained whatever garbage was used to initialize the stack value in invoke_popup_callback. This would lead to possible crashes when calling clear_tv(&rettv). Rather than rely on action at a distance, explicitly initialize rettv's type to VAR_UNKNOWN so clear_tv can tell nothing needs to be done. closes: #13495 closes: #13545 Signed-off-by: James McCoy <jamessan@jamessan.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
