#488 Virtualdub2 crashes while executing a script with RunNullVideoPass()

[Daniel FAVRETTO]

Hi there !
I got an issue while running scripts together on VirtualDub2 release 44282 and AviSynth+ release 3.7.3_20230715 on my PC running W10 (see also https://forum.doom9.org/showthread.php?t=185381).

These 2 scripts running together make VDub2 crash :
[U]Job.jobs[/U] :
VirtualDub.Open("Script.avs","",0);
VirtualDub.video.SetMode(0);
VirtualDub.RunNullVideoPass();
VirtualDub.Close();
[U] Script.avs[/U] :
BlankClip(pixel_type="YV12").SubTitle(VersionString())

These 2 scripts are running OK :
[U]Job.jobs[/U] :
VirtualDub.Open("Script.avs","",0);
VirtualDub.video.SetMode(0);
VirtualDub.SaveAVI("Dummy.avi");
VirtualDub.Close();
[U] Script.avs[/U] :
BlankClip(pixel_type="YV12").SubTitle(VersionString())

Therefore this issue is related to the use of the RunNullVideoPass instruction, because there is no crash if this instruction is replaced. I am using this replacement as a workaround, but I hope it will be temporary.
Thank you for your support.
