Comment (by jdlh):

 Tested with ffmpeg 4.1 as released by the FFmpeg project. The bug is fixed
 in version 4.1.
 {{{
 ffmpeg -report -v +repeat -to 0.3 -i fate-suite/h264/interlaced_crop.mp4
 -an -vf
 "crop=x=print(1234000+n)*0,zoompan=d=1:s=qhd:zoom=print(2718000+in)*0+print(3142000+on)*0+1"

 ...[omitted here for brevity] ...
 }}}
 Note that the values for '''n''', '''in''', and '''on''', shown in the
 last three digits before the decimal point, are equal now, and start from
 0. They differed before

 The full ffmpeg report output (with the fate-suite path prefix deleted
 because it had my filesystem info in it) is:
