Comment (by YellowOnion):

 ffmpeg -report -f lavfi -i nullsrc=duration=10:size=<matching-size> -i
 <input> -filter_complex "[0:v] [1:v] concat=2:1:0 [v]" -map "[v]" -f null
 -

 This is about as minimal as I can get it, I've tried it with 4 different
 files, surely it's

 using showinfo seems to ignore -d option for some reason, my biggest
 problem is that it only happens after 35mins of video, I cannot reproduce
 the bug in a shorter video length, using showinfo produces a ridiculously
 sized file
