(y or n) y --- As you can see I get a segmentation fault after the call to the gdk_flush [1] function. >From this program stack, I am unable to guess what could be the problem. Maybe a communication problem between GTK+ and libX11/libxcb but why? I was able to run this application in the past so I think I did something wrong when I built my 32-bit GTK+ this time. Can you guess where the problem is from this backtrace? Thank you.
