Sigsegv when attempting to access a color struct value.

["Ian King" <king eiffel com>]

I have the following code that works perfectly when running locally, but
fails when run as a remote client (when using the same pixmap).  Can anyone
help?

This is approximate what my code is doing, ignore any incorrect casting as I
am using a wrapper library in Eiffel to access gtk c external functions.


1) a_gdkimage = gdk_image_get (a_gtk_pixmap, 0, 0, width, height);
2) a_colormap = gdk_colormap_get_system ();
3) a_pixel = gdk_image_get_pixel (a_gdkimage, 0, 0);
4) a_color = (a_colormap->colors) + (a_pixel * sizeof (GdkColor));

The value of  'a_pixel'  is 16777215.  When I try to access the red value
from the returned color (line 4), I receive a segmentation violation signal,
but only if the client is ran remotely.  Is it anything to do with getting
the gdkimage from the pixmap?

Thanks for your time.
