the above Segmentation fault (core dumped) occurred when we use our 
output.cod(this file is generated by 
codec-g729-read-only/g729_decoder/source/coder/coder.c only).

but if we use the original
(by default => codec-g729-read-nly/g729_decoder/source/decoder/output.cod ) 
from svn source path it works.

if we use other then this file it's crashed why...?

could please help me
