New issue 362 by [email protected]: Patch 721: Segfault while resizing gvim
in 1 out of 10 cases if set list is on and lcs_eof is empty
https://code.google.com/p/vim/issues/detail?id=362
What steps will reproduce the problem?
1. Compile vim 7.4 Patchlevel 721
2. gvim -u NONE -U NONE -c 'set list lcs=' file_with_text.txt
3. Resize gvim-Window
[I'm pretty sure this problem was introduced in Patch 721. I cannot
reproduce the problem in Vim 7.4 Patchlevel 720.]
In about 10% of the cases(=resizements) I get an segfault (see below).
What is the expected output? What do you see instead?
Excpected: No Segfault; show Text-File in resized window.
What version of the product are you using? On what operating system?
Vim 7.4 Patches 1-207,209-721 on Fedora 21.
Please provide any additional information below.
