Hi. I'm getting different diff results on Linux and on OS X. I've replicated the results on 2 different Linux boxes. Something seems to be triggering diff to bail out on Linux. I've set timeout=None, so it doesn't seem to be a timeout issue. Tested on python 3.7, 3.8 and 3.9 with the same results.

I can't replicate the problem using the upstream source for python3 diff_match_patch. Could that indicate the source of the problem?

I've pasted some sample code showing the error below, and I've pasted copies of the expected and incorrect output.

Is there anything else I can do to help track down this problem?
