 Summary of the bug:

 OS: Win 10 Pro x64 1909

 How to reproduce:
 % ffmpeg -f concat -safe 0 -i mylist.txt -c copy output.mkv

 '''Latest working version:''' ffmpeg-20200504-5767a2e-win64-static (build
 from zeranoe)
 '''Defective Builds:''' ffmpeg-20200510-fc99a24-win64-static and newer

 Additional information:
 When doing concat on windows ffmpeg will take the "m" of '''m'''ylist.txt
 and add it to the path of the referenced files in that text file.

 In that picture example it cant find: "'''c'''out0.mkv-av1.ivf" because
 the "c" is from the '''c'''hunks.txt

 That issue is also being experienced by multiple users on multiple
 compiles. Linux users might also have a problem. Not 100% confirmed yet.
