Whenever a shared lib is loaded, the loader changes some addresses in the code depending on where the object was loaded to. I think this is not correct if compiled with -fpic and the reason why -fpic exists i.e. for performance reasons or because you have a loader that's not able to relocate or because you need multiple copies in different locations or for many more reasons.

Why not always use -fpic?

@Jay - because it will required one more calculation (the function address) for each function call. So performance-wise, if not needed it is better not to use it.
