Description schlaffi 2016-07-13 00:38:24 UTC

Description of problem:

aspell crashes when the the terminal size changes

Version-Release number of selected component (if applicable):

aspell-0.60.6.1-13.fc24.x86_64

How reproducible:

always, tested xfce4-terminal, xterm, and screen, 

Steps to Reproduce:
1. $ aspell check .bash_history
2. resize terminal emulator

Actual results:

segfault

Expected results:

aspell's ncurses interface adapts to the new size, or, at least, do not crash

Additional info:

hunspell works, so it is not an obvious ncurses bug. Also this bug is pretty new, although I can't tell when it occurred first, maybe on fc22->fc24 :( It also crashes on the console with screen and split screen, C-a S.

Comment 1 Nikola Forró 2016-07-13 14:33:04 UTC

Here is the problematic code:

delscreen(term);
term = newterm(0, stdout, stdin);

ncurses in Fedora 24 are built with SCREEN-extensions (sp-funcs) enabled, but there is a bug causing the above code to crash. The bug is resolved in the following upstream patch:
