[Iup-users] segfault using Lua iup.list dropdown on ubuntu 16.10

Hi,

A user of an Lua IUP application I maintain (chdkptp) reported crashes
on several recent Linux distros, including ubuntu 16.10, Fedora 25 and
Manjaro.

The crash appears to be triggered when a iup.list with dropdown set is
mapped, and can be reproduced using just the list.lua example included
with IUP.

This happens on ubuntu 16.10, and not on 16.04 (both x64, default
installs with unity desktop). I used the pre-built libraries from
sourceforge, but the user reported IUP built from source on the
affected distros has the same problem.

I reproduced the crash with the following:

Download iup-3.20-Lua52_Linux44_64_bin.tar.gz

Download http://webserver2.tecgraf.puc-rio.br/iup/examples/Lua/list.lua

Run
LD_LIBRARY_PATH=`pwd` ./lua52 list.lua

If the definition of list_dropdown is commented out, or list_dropdown
is not included in frm_prize it does not crash.

The crash gives a stack trace like:

LD_LIBRARY_PATH=. gdb --args ./lua52 list.lua
GNU gdb (Ubuntu 7.11.90.20161005-0ubuntu1) 7.11.90.20161005-git

Hi,

I only have Ubuntu 16.04 installed. But I think the problem should be
with the GTK version. It is using GTK 3.18 and as you mention it is
working. I installed all updates and it is still working. It used to be
simple to update to .10 version but I'm missing the path...

Can you check which is the GTK version where the problem is occurring?

Best,
Scuri

On Ubuntu 16.10, libgtk-3-0 is 3.20.9.

I agree GTK version seems likely to be the cause.

16.04 is an LTS release, so you have to change some setting to update
to 16.10, described on https://wiki.ubuntu.com/YakketyYak/ReleaseNotes

Thanks for looking into this

Hi,

Just fixed and commited to SVN:

Fixed: crash at IupList in GTK 3.20 when DROPDOWN=Yes and EDITBOX=NO. But
in that case keyboard, focus and enter/leave window callbacks stopped
working.

GTK changed how things are done for the control and those callbacks are
not working anymore. There is still work to do, but the crash is gone.

Best,
Scuri

I know this is a late reply, but FWIW I verified that that IUP 3.21
resolves the dropdown segfault under ubuntu 16.10 for my application.
Thanks again!
