Is there a recommendation by transcode developers of what to use
instead of tcrequant?

I checked the archives a bit and it looks like tcrequant does have a
bad bug track which could explain the random corruption you experience
(random in the sense that building it in one environment produces a
functional build and in another a bad one).
