 I'm trying to create GIF from series of JPG images using palette but
 processing completely stall. I'm using last static build
 (http://johnvansickle.com/ffmpeg/). Same behavior reproduced on older
 build (I'm try some 2015 year release), also 32 and 64 bit builds. I tries
 to resize pictures, remove EXIF data, change colorspace.

 I'm using Debian (3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u6
 (2015-11-09) x86_64 GNU/Linux) on VMWare.

 Firstly i'm generating a palette:
 {{{
 ffmpeg -nostdin -i 6659679_%04d.jpg -vf palettegen -y palette.png
 }}}

 Next I'm trying to create GIF:
 {{{
 ffmpeg -y -framerate 2 -i 6659679_%04d.jpg -i palette.png -lavfi
 paletteuse 6659679.gif
 }}}

 And got ffmpeg stall on second frame:
