patch 9.1.0069: ScreenLines may not be correctly initialized, causing hang Commit: https://github.com/vim/vim/commit/fd472655a93fd539c731c8daf3adc4e65ddce341 Author: Olaf Seibert <rhialto@falu.nl> Date: Thu Feb 1 21:11:16 2024 +0100 patch 9.1.0069: ScreenLines may not be correctly initialized, causing hang Problem: ScreenLines may not be correctly initialized, causing hang (Olaf Seibert, after 9.0.0220) Solution: always initialize ScreneLines when allocating a screen (Olaf Seibert) ScreenLines and related structures could be left uninitialized causing a screen update to run into an infinite loop when using latin1 encoding. Partly caused because by patch 9.0.0220, which makes mb_ptr2len return zero for NUL related: #12671 closes: #13946 Signed-off-by: Olaf Seibert <rhialto@falu.nl> Signed-off-by: Christian Brabandt <cb@256bit.org>
