x264 crash

[DaRtHmAuL]

Hi,
i encountered some problems to encode HD (720P) with x264 (669i_pulldown by Trahald). I got this error :

mv: l1r0 (-288,488)
limit: 480
mb_xy:73,9
completed: 264
Assertion failed: 0, file encoder/analyse.c, line 2832

This application has requested the Runtime to terminate it in an unusual way.

This is the AVS script i used:
DirectShowSource("I:\HDTV\video\video.grf",framecount=196061,fps=23.976,audio=false)
AddBorders(0,96,0,96)
ConvertToYV12()

Here are my x264 commands:
"I:\HDTV\x264.exe" --pass 1 --bitrate 7750 --stats "film.stats" --vbv-init 1.0 --aq-strength 0.25 --aq-sensitivity 5 --keyint 12 --min-keyint 4 --mvrange 511 --nal-hrd --vbv-maxrate 25000 --vbv-bufsize 14745 --level 4.1 --bframe 2 --b-rdo --weightb --bime --ref 3 --mixed-refs --deblock 0:0 --qcomp 0.75 --ipratio 1.10 --pbratio 1.10 --partitions "all" --8x8dct --me "hex" --subme 7 --threads auto --no-fast-pskip --aud --sar 1:1 --deadzone-intra 6 --deadzone-inter 6 --non-deterministic --progress --output NUL "I:\HDTV\video\video.avs"

"I:\HDTV\x264.exe" --pass 2 --bitrate 7750 --stats "film.stats" --vbv-init 1.0 --aq-strength 0.25 --aq-sensitivity 5 --keyint 12 --min-keyint 4 --mvrange 511 --nal-hrd --vbv-maxrate 25000 --vbv-bufsize 14745 --level 4.1 --bframe 2 --b-rdo --weightb --bime --ref 3 --mixed-refs --deblock 0:0 --qcomp 0.75 --ipratio 1.10 --pbratio 1.10 --partitions "all" --8x8dct --me "hex" --subme 7 --threads auto --no-fast-pskip --aud --sar 1:1 --deadzone-intra 6 --deadzone-inter 6 --non-deterministic --progress --output video.264 "I:\HDTV\video\video.avs"

Thanks

Bye

What happens if you use another input script? I think it is more likely you have a source filter that is crashing.

Yes i think you're right, it seems to be my source. I'm trying to reencode with new graphedit file. If it refuse to work, i will test with another type of source.
Thanks you

Edit: I'm working with AviSynth v2.5.7 and tried the latest release of v2.5.8a with no luck. The AVS script doesn't want to play at all. It's strange because it already worked. Perhaps i missed something.
