Hi all,

I just installed a new Windows 8.1 x64 computer and each time I launch the GTK2 GUI of master branch, I get a silent crash.
After generating a memory dump and loading it in windbg, I could see that it crashes in gtk_init call:

After doing a bisection, I noticed that it started appearing when we switched to GTK+ 2.24.23:

    Build with GTK+ 2.24.23.

But at the same time 1.12.0 release uses the same GTK2 package and works fine, so I'm puzzled. the amster x86 package works fine.

I tried upgrading the GTK2 package thanks to the download-mingw-rpm.py but the latest packages from OpenSUSE seem to lack some libraries.

I'm a bit out of ideas for now. Anyone familiar with this kind of issues?

Can you run the exe under WinDbg or even Visual Studio debugger to catch it in the act of crashing?

Are the gtk pdb's available anywhere?
