Hi!
I was just trying to use clang++ to compile my gtkmm application and I
went to this error:

If you are using a distro package of glibmm, please ask your distro to
update its glibmm package.
Will do! (I'm on ArchLinux)

Good morning/day/evening,
I am willing to use C++ binding for GStreamer in my application, developed
in VS under Windows.
I've found a question in this list from 2011 - the answer was that
gstreamermm support on Windows was planned but not yet implemented. Has
something changed in this years?

Perhaps so. That would certainly explain the crash if 'gobject_' was
NULL - but as I try to debug this issue things become even
Yes, G_OBJECT_GET_CLASS(gobject_) dereferences gobject_.
on_hide() should not be called when gobject_ is 0. Two possible reasons
it is called:
1. There is a bug in gtkmm 3.7.12 and 3.8.0 that can make such a call
happen.

No crash when I run it on Linux (Ubuntu 13.10). When on_hide() is
called, gobject_ is not 0. I used gtkmm 2.24.4 instead of 2.24.2. I
would be surprised if that matters.
Seems quite similar to the problem you described in

Many thanks for the suggestions guys. This problem has stumped me for
nearly a fortnight so I do appreciate your help!

What happens if you provide a destructor (empty of course, but not

Actually I did try that earlier
