Description:

Hi,

My colleague (Kamil Ignacek - author of cdw) found a bug in ncurses - http://permalink.gmane.org/gmane.comp.lib.ncurses.bugs/3559


Steps to reproduce:

1. Install cdw form AUR.
2. Run cdw and choose "Write image to disk".
3. Navigate to directory which name is 51+ characters long.
4. cdw crashes.

Backtrace:

please attach the patch. That PKGBUILD downloads a tarball with a script which applies the patch (WTF?)

OK
   PKGBUILD (2.7 KiB)
   set_field_buffer.patch (0.4 KiB)

Allan, maybe you could apply all the patches (from 2008.11 to 2010.11) because ncurses 5.7 in Arch is pretty old (2008.11).
Comment by Allan McRae (Allan) - Monday, 15 November 2010, 05:39 GMT
I do not want to apply those patches as that is really the developmental branch of ncurses. From experience, these can result in needing to do unexpected rebuilds/ I will stick to the latest stable release and apply bug fix patches as necessary.
