MeGUI stopped encoding audio at 89%

Hi. I've been editing lots of similar vids using the same method (MeGUI) and suddenly encountered a strange issue with this script:

c=trim(80365,80687).amplify(0).fadein0(25).fadeout0(20)
d=loop(50,81104,81104).trim(81104,81104+49).amplify(0).fadein0(49)++trim(81104,81423).amplify(0)++trim(81104,81424).amplify(0).reverse++loop(50,81104,81104).trim(81104,81104+49).fadeout0(49)
e=loop(425,81103,81103).trim(81103,81103+424).amplify(0).fadein0(25).fadeout0(25)
loop(90,79960,79960).trim(79960,79960+89).amplify(0).fadein0(25)++trim(79960,82626).amplify(0.15).fin(50)++trim(82627,85256).amplify(0.12)++c++c++c++d++e

The 'encoding audio' phase stopped at 89% and just stuck there - MeGUI didn't abort or issue a warning. I ended up encoding the main section, the c++c++c followed by d++e and then used mkvtoolnix to join the 3 clips.

I wonder, though, if anyone can suggest why the original script failed in the manner described? Many thanks.

Maybe you reached some limit (4 GB) of (intermediate) audio format or file system? Show complete MeGUI log.

The log is all standard looking stuff but doesn't have a lot to say about the audio problem:
[Information] [17 Oct 2018 15:02:33] Process started
--[Information] [17 Oct 2018 15:02:33] Standard output stream

---[Information] [17 Oct 2018 15:02:33] qaac 2.67, CoreAudioToolbox 7.10.9.0

Anyway, I'm not too bothered since I did manage to make my file using a roundabout method.

fin(50)++trim(82627,85256).amplify(0.12)++c++c++c+ +d++e

What's the fin function?

[pooksahib]

Hi hello_hello. It's to fade the sound in or out (fin / fout) without affecting the video.

function fin(clip input, int "num_frames")
{
num_frames = Default(num_frames,150)#25fps x 6secs = 150
FadeIn0(input,num_frames)
return AudioDub(input,last)
}

function fout(clip input, int "num_frames")
{
num_frames = Default(num_frames,200) #25fps x 8secs = 200
FadeOut0(input,num_frames)
return AudioDub(input,last)
}

Ahhhh... I thought it might have been a typo and maybe that was the cause. Obviously not.
