I think you missed my response to the previous problem that I had inserted in 
between text. My system defines SSIZE_MAX macro as 2147483647. Obviously, dar 
was using 102400 (It's 100K, right ?). So I reduced it to 10240 and it all 
started working. Thanks a lot..Will let you know on what I find with stat. I 
use gdb - but I haven't yet tried to debug the issue with stat.
