Actually, it certainly a bug, because the line should read

  memory->free( memory )

I've fixed this on the CVS.

By the way. You should call FT_Done_FreeType if you want to destroy
the memory manager. Otherwise, simply call FT_Done_Library(), it
will destroy the FT_Library and all child objects, and leave you
the care of cleaning the FT_Memory
