patch 9.0.1988: Vim9: potential use-after-free for class members Commit: https://github.com/vim/vim/commit/d2f4800099733216e28d59e1a5710f624b0d9ec1 Author: Yegappan Lakshmanan <yegappan@yahoo.com> Date: Thu Oct 5 20:24:18 2023 +0200 patch 9.0.1988: Vim9: potential use-after-free for class members Problem: Vim9: potential use-after-free for class members Solution: Use the class-related grow array for storing the member type instead of using a temporary type list grow array Use the type list grow array associated with the class than using a temporary type list grow array to allocate the class member type. For simple types, a predefined type is used. For complex types, the type is dynamically allocated from a grow array. For class variables, the type grow array in the class should be used. So that the lifetime of the type is same as the lifetime of the class. closes: #13279 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Yegappan Lakshmanan <yegappan@yahoo.com>
