Description of problem: After compiling a program against mingw32-gtk+ and deploying it in a windows XP box with the ming32-gtk+, it randomly crashes after within a GtkFileChooserDialog. As a comparison I downloaded gtk+-bundle_2.24.8-20111122_win32.zip and compiled and deployed with this version, which eliminated the bug. Version-Release number of selected component (if applicable): mingw32-gtk2-2.24.8-2.fc17_cross.noarch How reproducible: The gtk program crashes (almost) every time I click on a bookmark in the GtkFileChooserDialog and in random other places. Steps to Reproduce: 1. Create a gtk program that pops up a GtkFileChooserDialog. 2. Cross compile. 3. Deploy and run on windows Actual results: After interacting with the Dialog the program crashes. Expected results: No crash. Additional info: If needed I can create a minimum example including an example program, and a script compiling and creating a zip file for deployment.
This does not seem to apply to a package from the fedora project. Our current rawhide package would be mingw32-gtk2-2.24.8-1.fc17.noarch
This package is from the mingw-w64 testing repo which contains packages which will be merged back to Fedora when the legal approval for mingw-w64 is in: https://fedoraproject.org/wiki/MinGW/CrossCompilerFramework As bugreports for packages in this testing repo are appreciated (we want to have them fixed before everything is merged back to Fedora) I'm reopening this bug for now. @Reporter: a minimal testcase would sure be welcome to investigate this issue! That way we can also integrate it in our testsuite to make sure this bug doesn't re-appear in the future: http://fedoraproject.org/wiki/MinGW/Testsuite If you could also manage to get a gdb backtrace that would be really helpful as well (the mingw32-gdb package contains a gdb.exe)
Created attachment 552470 [details] Example program illustrating the bug
Created attachment 552471 [details] compilation script for test program
Created attachment 552479 [details] build win32 runtime environment for example program I have attached three files illustrating the bug. To reproduce do the following: 1. Save the three files in a directory. 2. Run ./compile.sh to compile. 3. Run ./build-win32.sh to build the win32 runtime environment 4. Copy the run time environment to a windows box and run test-gtk-dialog.exe 5. Press the open button. 6. Repeatedly press shortcuts and drives in the right hand margin until program crashes. Unfortunately gdb does not give much info about the source of the crash. For that I need a glib and gtk libraries with debug info. In any case here is the gdb trace: (gdb) run Starting program: h:\dov\gtk-dialog\win32\bin/test-gtk-dialog.exe [New Thread 2108.0x49c] [New Thread 2108.0x850] [New Thread 2108.0x7d8] [New Thread 2108.0x5f8] [New Thread 2108.0x5f4] Program received signal SIGSEGV, Segmentation fault. 0x61930dcc in ??

Thank you for the testcase! With it I managed to reproduce the crash. Investigating now..
Here's a proper gdb backtrace (created by placing the .dll.debug files from the mingw32-glib-debuginfo and mingw32-gtk2-debuginfo packages in the same folder as the other .dll files): C:\Documents and Settings\Erik van Pienbroek\Desktop\mingw>gdb test-gtk-dialog.e xe GNU gdb (GDB) 7.3 Copyright (C) 2011 Free Software Foundation, Inc.

This bug also exists in the package mingw32-gtk2-2.24.8-1.fc17 (which is currently in Fedora rawhide and uses the mingw.org toolchain) so this does look like a generic win32 issue
I suspect this GLib bug to be the culprit: https://bugzilla.gnome.org/show_bug.cgi?id=666296 This is already fixed in glib 2.31.6. As we're currently still using glib 2.31.2 (in both Fedora and the mingw-w64 testing repo) now will be a good time to update mingw32-glib2 to the latest available version.
This GLib bug may even be more interesting: https://bugzilla.gnome.org/show_bug.cgi?id=666551 There they explicitly mention the GtkFileChooser. That issue should be fixed in Glib version 2.31.8 (which is the latest available version) and I'm just about to push an update to that version (to both Fedora and the mingw-w64 testing repo)
Any progress with the preparation of the new packages?
In the Fedora rawhide repository a new mingw32-glib2 package was pushed. Some days ago a mass rebuild was done against gcc 4.7. For the mingw-w64 testing repository we also updated to the latest mingw-w64 trunk snapshot before rebuilding all packages. Unfortunately during this mass rebuild several packages failed to build. The mingw-glib2 package was one of them. See http://lists.fedoraproject.org/pipermail/mingw/2012-January/004386.html for more details about that. A fix for the mingw-glib2 build failure (and various other failures) was pushed to mingw-w64 trunk yesterday. Right now I'm running another mass rebuild to find out if the mingw-glib2 build failure is really resolved now. Once the new packages are ready I'll leave a comment in this bugreport.
New packages have been pushed to the testing repo. With these packages I wasn't able to reproduce the crash anymore. Is the issue resolved for you if you update to these packages? Here are the packages I've used: mingw32-atk-2.2.0-2.fc17_cross.noarch mingw32-cairo-1.11.2-2.fc17_cross.noarch mingw32-gdk-pixbuf-2.24.0-3.fc17_cross.noarch mingw32-glib2-2.31.12-1.fc17_cross.noarch mingw32-gtk2-2.24.9-2.fc17_cross.noarch mingw32-libffi-3.0.10rc8-2.fc17_cross.noarch mingw32-pango-1.29.4-2.fc17_cross.noarch
I just tested with two of my programs including a multi-thread program that was unusable with the previous mingw32 versions, and everything is stable now. Thus the problem seems to have been resolved. Thanks a lot!!
You're welcome. Closing bug
