[gtkada] 64bit linux runtime problem with gtkada 2.4.0

[Darel Cullen]

Hi,
I compiled and installed GtkAda-2.4.0 on my amd64 system running pure 64bit 
linux. everything in gtktest works apart from GtkAda Canvas widgets 
(dragging and dropping boxes).

as soon as i click on the canvas i get a segmentation fault with the 
following dump

Program received signal SIGSEGV, Segmentation fault.
