Can you please check if either the old or the new eac3to build (or both) are reporting that? Or do both *not* skip identical frames for this track?

Both eac3to 3.28 and 3.29 does the same in that regards, reports skipping and does a second pass:

I'm very curious why eac3to creates different results for the FLAC or WAV(s) depending on wich decoder is used when it comes to seamless branching and overlapping audio.

eac3to "bluray-folder" 1) 3: "audio.flac"

Using a line like that three times, adding either "-dcadec" or "-sonic" creates differences between the results, rather small diffrences but still, diffrences from lossless to lossless.
Take Taken 3 for instance where there is 332088173 samples (332 MILLION) in the FLAC-track, all 3 decoders gives the exact same amount of samples, and between arcsoft and sonic 3650 samples differ, dcadec vs. sonic 3736 differ, dcadec vs. arcsoft 3670 samples differ.

But if you extract the DTS MA track first:

eac3to "bluray-folder" 1) 3: "audio.dtsma"

And then do, using each decoder:

eac3to "audio.dtsma" "audio.flac"

The resulting file is bitidentical (except in the case of Taken 3, dcadec reported an error and exited)
