patch 9.0.2107: [security]: FPE in adjust_plines_for_skipcol Commit: https://github.com/vim/vim/commit/cb0b99f0672d8446585d26e998343dceca17d1ce Author: Christian Brabandt <cb@256bit.org> Date: Tue Nov 14 20:05:59 2023 +0100 patch 9.0.2107: [security]: FPE in adjust_plines_for_skipcol Problem: [security]: FPE in adjust_plines_for_skipcol Solution: don't divide by zero, return zero Prevent a floating point exception when calculating w_skipcol (which can happen with a small window when the number option is set and cpo+=n). Add a test to verify Signed-off-by: Christian Brabandt <cb@256bit.org>
