Yeah, some of these failures are due to numerical unstabilities in tests
(nasty ones, still fighting) and some simply to crappy code (HMMs are
hopeless :( ).

Now, with regards to the actual failures induced by the new branch, it
took me a while to understand why they where happening, and now I realise
that we probably should have explicit coercions at these locations.
