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.
