I do have all errors turned on.
As I am using linked lists the most easy way to check for the last item is 
to check on NULL in the next part.
It should while debugging also generate an error if I have made an error.

At this moment I found a typing error in some other part of the program 
which is used in a Task using OpenGL.
It seems that that was the error.

I would declare these variables as not null access whatever, to get an
exception on assignment to them, rather than waiting until the error
manifests as a segv. (Do you have a lot of checks turned off, so that it
doesn't raise Storage_Error)?
