#9600: Fieldmatch ppsrc crashes

-------------------------------------+-------------------------------------
Every attempt to use fieldmatch's ppsrc feature seems to crash ffmpeg
unless the two input streams are identical (?).
I've been trying to eliminate residual combing on fade in/outs so I tried:
{{{
ffmpeg -i .\source.mp4 -map 0:v -c:v h264_nvenc -tune lossless -vf
normalize preprocessed.mp4
ffmpeg -i .\preprocessed.mp4 -i .\source.mp4 -c:v h264_nvenc -tune
lossless -filter_complex fieldmatch=ppsrc=1 output.mp4
}}}
I've tried using -report but the log doesn't really list anything
interesting.
Windows' event viewer shows:
