conhost crash during encoding

[GoogleCodeExporter]

2-pass x264 encoding of MPEG-2 into MKV (with or without filtering, doesn't 
matter)

At random point of each encoding pass conhost error occurs (see attachment), 
which freezes the encoding process until the error dialog window is closed. 
After that the process continues.

Quite annoying problem, as it prevents from continuous no-watch encoding 
process.

Win7 eng, Xvid4PSP 5.0.37.177, .NET 4.0, x264 core 105 r1722

Please provide any additional information below.

I don`t know what to say, except that you are the only one who reporting this 
problem (atleast I didn`t heard anything similar).
And I don`t think that this is XviD4PSP fault. You can kill conhost process 
right after starting encoding - all will work fine. So it seems like it needed 
only for starting encoder process (run some_file.exe) and after that it not 
used. Why it crashes - I don`t know. You can try to find some info about this 
crash in the system log.

"2-pass x264 encoding of MPEG-2 into MKV"
Only with 2-pass encoding?
Only if the source file is MPEG2?
How "fast" it crashes (minimum time after starting encoding)?

I think that might be connected to the memory issue I experienced (issue #11). 
I have been running out of memory constantly during the encoding (OS Memory low 
warnings), so that might have been the reason of conhost failure. The last 
encoding didn't suffer from the lack of free memory and the conhost didn't fail 
even once, so the problem most probably is not Xvid4PSP directly.

Today I experienced conhost crash again. The memory consumption of Xvid4PSP at 
the moment of crash was ~1100Mb and the system had quite a while memory to 
spare, so no 'Memory low' warning appeared.
As far as I understand that won't help you to identify the problem anyway, so 
my question is if it's possible for encoding process to continue without 
awaiting for the confirmation of conhost 'Close program' OS dialog box?

Answering on your questions:
1) I use only this type of conversion, and right now I am too short of time to 
investigate other cases, sorry. May be later.
2) Usually it is 40-60 minutes from the start, but sometimes it happened after 
4-6 hrs. I guess it is more dependent on the memory usage, or some kind of 
system objects usage (GDI/handlers or whatever, I am not familiar with 
WPF/.NET/whatever is guilty mechanics)

I have a similar problem, so he's not the only one

This behaviour is not reproduced with the currently latest version 5.10.305.0 
(2012-09-13) RC32.1, so it can be closed.
