g_stat In src/glade3-3.8.5/gladeui/glade-utils.c At Line 1865 Causes SIGSEGV in strlen () from C:\Windows\System32\msvcrt.dll When Saving File

[TalkVideo]

When I run
/mingw64/bin/glade-3.exe

The program crashes, (segfaults), and file size is zero, after selecting or entering a filename, and clicking Save in the File Chooser Dialog.

I get:

Thread 1 received signal SIGSEGV, Segmentation fault.
0x00007ff90f48c981 in strlen () from C:\Windows\System32\msvcrt.dll

Whether installed by pacman or built from source,

When I enable debugging symbols I get more info as below, but at the top of the stack, it mentions the file and line below, and the problem has been isolated to that line.

(gdb) bt
#0 0x00007ff90f48c981 in strlen () from C:\Windows\System32\msvcrt.dll
#1 0x0000000068611286 in ?? () from C:\msys64\mingw64\bin\libglib-2.0-0.dll
#2 0x0000000068611f25 in ?? () from C:\msys64\mingw64\bin\libglib-2.0-0.dll

error=error@entry=0x0) at ../../glade3-3.8.5/gladeui/glade-utils.c:1865

When I change:
1865 retval = g_stat (filename, &info);
To:
retval = stat (filename, &info);

In
src/glade3-3.8.5/gladeui/glade-utils.c

I get:
warning: Invalid parameter passed to C runtime function.

But the program appears to save the file correctly.

If I hardcode it like this:
1865 // retval = g_stat (filename, &info);
1866 retval = 0;

I get a message about the filename being null, and it does not appear to save the file correctly, but it does not segfault.

Below is my history of Gtk2 and Glib Installation:

Glade is 3.8.5

Source:
pkgver=3.8.5
pkgrel=2

It was working fine before. Please fix it. Thx.

[peterbud]

For me glade-3 3.8.5 is working fine (using from the repo). However I'd suggest to use the much more up-to-date glade (3.22.1).

[TalkVideo]

I need a Glade that is suitable for Gtk2.

I use the newer Glade for Gtk3.

You may see the same error if you do a pacman -Syu

I think an update to mingw-w64-x86_64-glib2 did it. I will be testing earlier commits, as well.

[peterbud]

I have done pacman -Syu before I sent you my reply. Maybe @KrullBorg can also check, he is using glade AFAIK.

[KrullBorg]

the problem isn't well explained, but i get segfault on saving the file, and the file is 0 size; have you tried to update glade3 to 3.8.6?

[TalkVideo]

I apologize. I forgot to mention that it happens when I try to save a file. The program crashes, (segfaults), and file size is zero, after selecting or entering a filename, and clicking Save in the File Chooser Dialog. So, @KrullBorg you have duplicated it.

I will try upgrade. I was not aware 5.8.6 is out there. Thx.

[TalkVideo]

I looked here for 3.8.6:
http://repo.msys2.org/mingw/

None there. Do you mean source from https://glade.gnome.org/ or is there a mingw-w64-x86_64 package available for 3.8.6? Thanks.

[KrullBorg]

Merely update PKGBUILD file and rebuild it

[Alexpux]

@TalkVideo I'm upload 3.8.6 version. Try it

[TalkVideo]

Thanks.

I did have the same problem when building from 3.8.6 source downloaded from https://glade.gnome.org

I just tried glade-3.exe (3.8.6) installed via pacman -Syu

Same problem.

I have not yet tried a simple program with a call to g_stat() but I think the problem may actually be in glib-2.0. I will try reverting to a previous glib-2.0.

[TalkVideo]

See:
https://mail.gnome.org/archives/gtk-devel-list/2018-May/msg00033.html

Looks like there was an update, (and a backport) in glib2.

For the mingw-w64-glib2 Source Package, I am at commit:
6b196d8

Also in /var/log/pacman:
[2018-06-04 08:38] [ALPM] upgraded mingw-w64-x86_64-glib2 (2.56.1-1 -> 2.56.1-2)
[2018-06-04 08:38] [ALPM] upgraded mingw-w64-x86_64-glib-networking (2.56.0-2 -> 2.56.1-1)

But...
(Get-Item C:\msys64\mingw64\bin\libglib-2.0-0.dll).VersionInfo
returns:

ProductVersion FileVersion FileName

---

2.56.1 2.56.1.0 C:\msys64\mingw64\bin\libglib-2.0-0.dll

Looks like this update may not be in place yet. Still having the same problem. Checking further.

[lazka]

The fix was https://gitlab.gnome.org/GNOME/glib/commit/0bc1e98af6f6ed2f4a5f05f495b0c9a001dc370f

This will either be fixed with glib 2.56.2 or 2.58.0, which ever comes first.

[lazka]

The first fix is in, but this could also have been 9533ee7 which would need a rebuild of glade.

Is this still a problem?

[TalkVideo]

On MSYS2, MinGW64 Environment, it still is.

When running glade-3.exe, (Help->About Says 3.8.6)

pacman -Sl
mingw-w64-x86_64-glade3 3.8.6-1

When rebuilding mingw-w64-glade3 from source at commit:
2155c28

The problem persists.

When looking at the source of: mingw-w64-glib2 (Same Commit as above)
src/glib-2.56.1/glib/gstdio.c

I do not see the change to gstdio.c that is mentioned here:
https://gitlab.gnome.org/GNOME/glib/commit/0bc1e98af6f6ed2f4a5f05f495b0c9a001dc370f

Also, PKGBUILD starts as follows which is not the same as this commit:
Alexpux@9533ee7

_realname=glib2
pkgbase=mingw-w64-${_realname}
pkgname="${MINGW_PACKAGE_PREFIX}-${_realname}"
pkgver=2.58.1
pkgrel=1
url="https://www.gtk.org/"
arch=('any')
pkgdesc="Common C routines used by GTK+ 2.4 and other libs (mingw-w64)"

And then when I try to build with makepkg-mingw:

(I installed mingw-w64-x86_64-meson)

[lazka]

You need to update MSYS2 before installing new packages pacman -Suy

[TalkVideo]

Actually I did that and for whatever reason I still had the problem. Even after removing and re-installing glade, and even libglade, I think. Not sure what I may have missed.

However, on more than one machine with fresh install, or fresh update of MSYS2, the problem is gone.

Issue closed as far as I am concerned.
Thanks.

[lazka]

Thanks for testing
