This array is constrained but indeed enormous. It looks like a problem
with the Gdk.RGB package to me.
It could be changed to make the Rgb_Buffer type unconstrained.
The package body would need some changes too, for example
Rgb_Buf'Address changed to Rgb_Buf(Rgb_Buf'First)'Address
and an added check to see if Rgb_Buf is large enough and an exception
raised if not.
Perhaps a function could be added to calculate the necessary buffer size
based on image width and heigth?
