I noticed that your patch removes the call to vorbiscomment_entry_array_delete_()
in FLAC__metadata_object_vorbiscomment_resize_comments() function, and I think
that it reintroduces one place of a potential memory leak:

'object->data.vorbis_comment.comments' is a pointer to an array of
FLAC__StreamMetadata_VorbisComment_Entry structs, and these structs contain pointers.
So it's necessary to free all 'object->data.vorbis_comment.comments[i].entry' pointers
before freeing 'object->data.vorbis_comment.comments' pointer itself.
