I have found the location where the crash occurs:

     if (!(font->flags & FLAG_USED_CHARS_SHARED) && font->used_chars)

     if (font->used_glyphs)
       RELEASE(font->used_glyphs);
     if (font->encoding)


In the case of the example on Windows, font->used_chars seems to be
broken, though it is not NULL.

Best,
