In version 5.2.9
Warning: the turningnumber algorithms do not agree. The current computed value is -1, but the 'connect-the-dots' algorithm returned 0
In a word, no Martin gave this explanation a few weeks ago... This is produced by new metapost version, which is now included in the windows distribution. The turningnumber (used in therion to detect self-intersecting scrap outline) is not calculated perfectly in metapost, so another algorithm has been included to check the computation. If the algorithms give different results it means that you cannot be so sure that the scrap outline is really degenerated (and you can ignore therion's message about intersecting outline for that scrap).
