Following line which tries to use a pointer glyph as a text annotation
crashes both XEmacs-21.0-b59 and XEmacs-21.2-b5. They vanish without
a single line of good-bye.
(make-annotation gc-pointer-glyph nil 'text)
The built-in function `set-extent-begin-glyph' at line 161 of
annotations.el
(set-extent-begin-glyph new-annotation glyph layout))
is where it happens in lisp-land.
I don't know whether this is Windows-specific.
