[vlc-devel] Segmentation fault with rate control equation defined in x264 module

[Aurele]

Hi,
It's me again.

I'm working with VLC 0.8.6h on ubuntu Gutsy.
I've defined stats (statsfile name: "x264_2pass.log") and rceq (rate 
control equation: "blurCplx^(1-qComp)") parameters  in  x264 module.
I've no problem with compilation and installation. VLC works properly. 
But when  i try to encode in h264, i get this error:

x264 [info]: using SAR=1/1
x264 [info]: using cpu capabilities MMX MMXEXT SSE SSE2
[00000367] main encoder debug: using encoder module "x264"

[00000291] mux_mp4 private debug: adding input
Parser: missing ( in "x264_2pass.log"
Segmentation fault (core dumped)

And when i use gdb i get :

How can i avoid that ?  I think that the problem comes with the rceq.  
How can i well define rceq parameter in the x264 module ?

Any help is welcome. I really want your help.

Thanks,
