Adobe Flash CS3 Professional – Error

I found that Adobe Flash CS3 Professional gives following error in IDE ::

Location : , Line 1

Description : 5005: Unknown error optimizing byte code.

Source :

This is happening when I compile library of size 8+ MB, and that is having 250+ classes !!

Do any one know what is the exact reason behind this or any solution for this?
