linux - "while read line" giving garbage data while reading a C file

I want to write a small script of parsing all the comments of the C file using shell script but I am not even getting the read o/p correct,I am getting the file o/p mixed with other garbage data.

Here is what I am doing..

   parse_comments() {
    local filename="$1"
    while read line; do
    echo $line | grep "*"
    done < "$filename"
    parse_comments "/root/rpmbuild/linux-2.6.32-431.17.1.el6.x86_64/fs/inode.c"

I have tried all the solutions(like- while read -r, while read -u 3 and other too) told on SO for while read problem none of the solution worked for me.
I don't know whats wrong with read with while loop please help...
If I use 'awk' for the same work it works fine. But 'awk' doesn't serve my purpose.
