Well I have managed to copy a .ts which has the problem, had to record over 8
hours of tv just for this.
Run the command line and around 8.02 seconds it fails.
Now this is with version ffmpeg version N-78956-g920f592 and ffmpeg version
3.0.2

minimum command line is
ffmpeg -i failure_chomped.ts -c:v libx265 -c:a libfaac -async 1 -y -f failure.ts
or add a scale for faster testffmpeg -i failure_chomped.ts -c:v libx265 -vf
'scale=640x360' -c:a libfaac -async 1 -y -f failure.ts
output gives
encoder@encoder:~$ ffmpeg -i failure_chomped.ts -c:v libx265 -c:a libfaac -y -f

Im reporting this as a decoding issue due to the fact that 2 different
machines using 2 different encoding backends fail the EXACT same way, and when
they fail the encoded picture looks EXACTLY the same on both outputs.
I will start a TS Recording and then try and chop this up to get a small TS
with the failure but as the stream is HD at source will be a big recording.
The command lines for the 2 encodings are different as one use x265 and the
other a bought in hardware encoder.

If the issue you see is not reproducible with current FFmpeg, there is
nothing that we can fix.

Sorry, I am not a native speaker and I find this difficult to understand:
Are you reporting a decoding issue? How is it related to the encoding
properties you describe above?

How does the command look that you are currently using to decoder? If
you provide it, it should be easy to know how to capture.
