Thanks. I see two possibilities to fix the bug.
(1) Avoid lazy copying in `FT_Get_Glyph'.
(2) Update the documentation:
By default, `FT_Get_Glyph' can be used only once.[*] If you want
more copies, use either `FT_Copy_Glyph' or call
`FT_GlyphSlot_Own_Bitmap' before calling `FT_Get_Glyph' again.
What do you prefer?

Yep. This must be fixed.

[*] This statement is valid only for FT_GLYPH_FORMAT_BITMAP objects.
For FT_GLYPH_FORMAT_OUTLINE objects, FreeType always creates a
copy.
