And what happens if you simply print it with Ada.Text_IO?

In my experience, gdb sometimes (well, rather often) prints complex Ada 
structures incorrectly or incompletely.

Of course you could divide the code inte more cases, separating the 
comma case from the other cases.

That code is incomplete. Where is the "end if"?

If you want more help, please try to make a small, self-contained 
example in which the problem occurs, and show the whole code.

Why is gdb speaking of GObject? I tought "str" was mean to be 
Ada.Strings.Unbounded.Unbounded_String, not some Gtk type.
