+Subject: [PATCH] HEIF: keep reader callback table alive
+
+libheif retains the heif_reader pointer after
+heif_context_read_from_reader returns. The callback table was scoped
+to the non-sequential branch and could be destroyed before
+tiled image decoding used it from worker threads.
+
+Give the callback table static storage duration.
