This is a bug in your program. After FT_Done_FreeType() is called, every
memory allocated
by the corresponding FT_Library should be released (with the exception of
FT_Glyph objects
allocated by the user, but you are responsible for free-ing them before
FT_Done_FreeType())
Calling FT_Done_Face() after that is probably asking for a lot of trouble
(i.e. waling dangling pointers
in the heap).
