Because when I copied the classicfm.aac file to my test system I
stupidly changed the extension to m4a. Sorry about that.
I'm running v8.2.0, git-91db8512b from yesterday on my test system.
I've rerun the test and can confirm that I get 37 sync errors but the
file plays...with a few "blips" in the audio. I also get concealing
corrupted frames messages, which the stock firmware doesn't report or
appear to have similiar.
At least I can't find anything.

It's great to be able to confirm that the sync error code handles
works.
I've attached the full log file from the CF radio test.
