Thiago> 0. Start emacs with `emacs -Q'
Thiago> 1. Create some text composition, e.g. eval: `(insert (compose-chars ?+))'
Thiago> 2. Move cursor to before composed character
Thiago> 3. `M-x delete-forward-char' or press <delete> key
Thiago> * Backtrace:
Thiago> Debugger entered--Lisp error: (wrong-type-argument sequencep t)
Thiago> lgstring-glyph-boundary(t 1 2)
Thiago> delete-forward-char(1 nil)
Thiago> funcall-interactively(delete-forward-char 1 nil)
