Everything that is accessible from a FT_Face handle belongs to the object 
itself and
will be destroyed when FT_Done_Face is called. Each time you call FT_Load_Glyph,
the glyph data in face->glyph is re-written.

If you want to "extract" glyphs outside of the FT_Face, you should use something
like FT_Get_Glyph. The new FT_Glyph object is owned by you, and must be 
destroyed
by calling FT_Done_Glyph explicitely.

Finally, everything that comes from the cache is owned by it.

Hope this helps,
