Is it possible that echo command break the so file?

Is it possible that echo command break the so file?

I want to add version string to my so file, then I use:
echo "v1.01" >> aa.so
and the version is add to the tail of aa.so
However, I wonder that if this method has any possibility that break the
so file? Or we can add infinite bytes to the end of a so file and will not
break its structure?
PS: Except for file signature, because aa.so is build by myself.
