OK. I can reproduce now with all 3 test cases. I tweaked the line sizes 
a little bit. Noting that it fails on 2.067.0 and 2.067.1 on Linux x64, 
but passes just fine on OSX same versions.

FWIW, you don't need anything except foreach(line; somefile.byLine()) {} 
as your main code.

I think the correct fix is to fix readln as outlined in Ranier's pull 
request: https://github.com/D-Programming-Language/phobos/pull/2794

But that seems to be stalled. I will at least try to fix the 
assumeSafeAppend calls so they are not crashing.
