MeGUI abruptly ends encode and shows "error" in queue on complex AVS script.

[The T]

As the title says. I'm encoding a really heavy AviSynth script. I can load it up in VirtualDub (and MeGUI) just fine and in MeGUI it will start encoding, but about 75% of the way through it abruptly ends with no video outputted. I've tried using AviSynth v.2.6.0 ST as well as AviSynth+. Both do the same thing, AviSynth+ just encodes the video faster.

One of the logs, which also includes my script, where it errors out is here: https://pastebin.com/tDTwUV98

My idiot workaround is just to encode half the video, encode the 2nd half, and then combine them into one video.

I'm still open to better solutions, though.

At a guess I'de say that its probably out of memory issues.
If you played clip from start in VDub2 together with TaskManager Performace tab open, you may see the memory usage rise steadily until OMEM at about same position as MeGUI crash.
