[wontfix for gtkmm-3] new-delete-type-mismatch on window close when compiled with -fsanitize=address

When you compile your application with -fsanitize=address, closing the window results in a new-delete-type-mismatch crash.

Example code

minimal.cpp
Based on: Programming with gtkmm 3- Simple Example

Compiling

g++ minimal.cpp -o simple `pkg-config gtkmm-3.0 --cflags --libs` -fsanitize=address

Executing

./simple

Once the program has started, click on the close button and you will see the following crash.
