In my ubuntu 20.04 and Windows 10, I installed GTKMM4 with VCPKG since the normal installation of GTKMM4 is not available.
Then I downloaded this example from the gnome tutorial page and added this cmake.
On clicking the close button, which calls the window hide, the app is crashing in Ubuntu alone and no issue is there in windows setup.
The backtrace is given below.
Thread 1 "gtkmmtes2" received signal SIGSEGV, Segmentation fault.

The issue is easily reproducible with any window and hide() function in Ubuntu. Also I'm seeing the following warnings with every gtkmm4 app in Ubuntu.
