patch 9.0.1830: Vim9: crash when accessing a null object Commit: https://github.com/vim/vim/commit/d7085a06358c22250a27186bb7d52112ed4addd1 Author: Gianmaria Bajo <mg1979.git@gmail.com> Date: Thu Aug 31 18:15:26 2023 +0200 patch 9.0.1830: Vim9: crash when accessing a null object Problem: Vim9: crash when accessing a null object Solution: Check accessing a NULL object in def function An object is NULL when the variable is declared, but the constructor isn't called. Accessing/setting a member on the object crashed Vim. Note: this happens inside def functions, at script level things work differently. Accessing a NULL object member results in E1360 (correctly), while setting a value on it results in E1012 (type mismatch) so there's still something to fix. closes: #12973 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Gianmaria Bajo <mg1979.git@gmail.com>
